Genesis 20

Today’s Passage: Genesis 20

You may have to read this chapter twice before you believe your own eyes, because it is a story you have already read once before. Years have passed since Abraham went down to Egypt and, out of fear, called Sarah his sister and nearly lost her to Pharaoh. He has stood under the stars and believed God. He has walked with God, argued with God for the city of Sodom, seen fire fall on the plain. And now, an older and wiser man, he journeys south to a place called Gerar, and there, gripped by the very same old fear, he tells the very same old lie: she is my sister. And once again a king takes Sarah into his house. But this time God does not wait for the king to blunder into the truth. God comes to Abimelech in a dream by night and stops him cold, telling him he is a dead man for taking a married woman. Abimelech, who has not so much as touched her, protests that he acted in the integrity of his heart, and God answers that He knows it, that in fact it was God Himself who held the king back from sinning. Then comes the line that will astonish you: return the man’s wife, for he is a prophet, and he will pray for you and you will live. And Abraham, the frightened liar, prays, and God heals the household and opens the wombs He had closed for Sarah’s sake. So the chapter holds a man who failed in the same way twice, and a God who guarded the promise anyway, and still called that man His own prophet.

As you read, hold this: God guarded the promise when Abraham failed, and still called him His prophet.

Genesis 20:1-2 (BSB)

¹ Now Abraham journeyed from there to the region of the Negev and settled between Kadesh and Shur. While he was staying in Gerar, ² Abraham said of his wife Sarah, “She is my sister.” So Abimelech king of Gerar had Sarah brought to him.

Watch how quietly the trouble begins. Abraham simply moves, as he has moved a hundred times, down into the dry southern country, and settles for a while in Gerar. There is nothing wrong with the journey. But then, in a single short sentence that the Bible does not pause to explain, the old fear surfaces again: Abraham said of his wife Sarah, she is my sister. He does not announce a plan or wrestle aloud with his conscience. He just says it, the way a man says a thing he has said before and no longer questions. And the consequence follows just as quickly. Abimelech, the king, hears that this traveling woman is unattached, and he has her brought to his house.

Do not rush past how serious this is. Sarah is the wife the promise runs through, and Abraham has once more handed her over to protect himself. It would be easy to shake your head at him, and there is a warning here for all of us, that a fear we never put to death will rise again at the worst moment. But hold your judgment for one more scene, because the striking thing about this chapter is not what Abraham does. It is what God does while Abraham sleeps unaware of the danger he has walked his wife into.

Genesis 20:3-7 (BSB)

³ One night, however, God came to Abimelech in a dream and told him, “You are as good as dead because of the woman you have taken, for she is a married woman.” ⁴ Now Abimelech had not gone near her, so he replied, “Lord, would You destroy a nation even though it is innocent? ⁵ Didn’t Abraham tell me, ‘She is my sister’? And she herself said, ‘He is my brother.’ I have done this in the integrity of my heart and the innocence of my hands.” ⁶ Then God said to Abimelech in the dream, “Yes, I know that you did this with a clear conscience, and so I have kept you from sinning against Me. That is why I did not let you touch her. ⁷ Now return the man’s wife, for he is a prophet; he will pray for you and you will live. But if you do not restore her, be aware that you will surely die—you and all who belong to you.”

Here is the turn of the whole chapter, and it comes with that small word again: however. Abraham had said his lie and gone to sleep, but God does not sleep. One night God comes to Abimelech in a dream and speaks with startling directness. You are as good as dead, He says, because of the woman you have taken, for she is a married woman. God will not let this go forward. He steps into a pagan king’s bedroom, so to speak, and stops the sin before it can happen.

And listen to Abimelech, for he answers with real dignity. He had not gone near her, and he pleads his case honestly. Would You destroy an innocent nation? He was deceived. Both Abraham and Sarah told him she was unattached. I have done this in the integrity (תֹּם) tom, pronounced TOME. Strong's H8537, completeness, wholeness, integrity, innocence. When Abimelech says he acted in the integrity of his heart, it means completeness, wholeness, a heart that is not divided or double. It is the sound of a man saying, I was not scheming, my conscience was clean, my hands were empty of any wrong. And the remarkable thing is that God does not argue with him. God grants it, saying, yes, I know you did this with a clear conscience. There is a quiet honesty in the way the Bible tells this, letting a pagan king possess a genuine integrity in this matter that the covenant man, in this moment, did not. It is a reminder that God sees the heart plainly, that He can tell true innocence from guilt, and that He deals justly with every person, inside the covenant and out. Give thanks for a God who reads us truly and never mistakes the honest heart for the guilty one. of my heart and the innocence of my hands, he says, and it is true. Then comes the tender part you must not miss. God agrees with him. Yes, I know you did this with a clear conscience, God says, and here is the wonder of it: so I have kept you from sinning against Me. That is why I did not let you touch her. It was not Abimelech’s own goodness that held him back. It was God, quietly restraining a man from a sin he did not even know he was near. How much of our own life is like that, guarded by a mercy we never see.

And then, most astonishing of all, God calls Abraham a prophet (נָבִיא) nāḇîʾ, pronounced nah-VEE. Strong's H5030, prophet, spokesman. This is the ordinary Hebrew word for a prophet, one who speaks for God and stands between God and people, and here is a thing worth stopping over: this is the very first time in all the Bible that the word appears. The first person ever called a prophet in Scripture is Abraham, and he is given the title in the middle of a story where he has just told a lie out of fear. You might have expected the word to be crowned on someone at his shining best. Instead God lays it on a man at his most fearful, and defines the prophet’s work not by flawlessness but by nearness to God, the one who hears God and can pray to God on another’s behalf. It is a picture of grace from its first appearance. God’s calling on a life does not wait for that life to be spotless. He names Abraham a prophet, then hands the frightened man an intercessor’s task, and Abraham rises to it. . Return the man’s wife, He says, for he is a prophet, and he will pray for you and you will live. Think of it. The man being defended has just lied. The pagan king is the one telling the truth. And yet God’s word for Abraham is not liar, not coward, but prophet, and He gives Abraham the honor of being the one whose prayer will save the very household his lie endangered. That is not because Abraham earned it. It is grace, plain and undeserved, covering a failing man and setting a mercy in his mouth.

Genesis 20:8-13 (BSB)

⁸ Early the next morning Abimelech got up and summoned all his servants; and when he described to them all that had happened, the men were terrified. ⁹ Then Abimelech called Abraham and asked, “What have you done to us? How have I sinned against you, that you have brought such tremendous guilt upon me and my kingdom? You have done things to me that should not be done.” ¹⁰ Abimelech also asked Abraham, “What prompted you to do such a thing?” ¹¹ Abraham replied, “I thought to myself, ‘Surely there is no fear of God in this place. They will kill me on account of my wife.’ ¹² Besides, she really is my sister, the daughter of my father—though not the daughter of my mother—and she became my wife. ¹³ So when God had me journey from my father’s house, I said to Sarah, ‘This is how you can show your loyalty to me: Wherever we go, say of me, “He is my brother.”’”

Morning comes, and Abimelech wastes no time. He rises early, gathers all his servants, and tells them the whole terrifying thing, and the men are afraid, for they understand that the household has come within a breath of destruction. Then the king summons Abraham and asks the questions a wronged but honest man would ask. What have you done to us? How have I sinned against you, that you would bring such guilt on me and my kingdom? You have done things to me that should not be done. There is a strange reversal here that you should feel the sting of: the pagan king is rebuking the prophet, and the rebuke is deserved.

And how does Abraham answer? Not well. He offers a tangle of excuses. First, he confesses the fear underneath it all: I thought surely there is no fear of God in this place, and they will kill me on account of my wife. That fear was old and deep, and it turned out to be wrong, for the fear of God was more alive in Abimelech than in Abraham’s guess. Then he reaches for the technicality, that Sarah really is his half-sister, the daughter of his father but not his mother, as if a fact could rescue a lie. And finally he admits this has been his practice all along, a standing arrangement he set up with Sarah wherever they traveled. It is a limp, half-true, self-protecting defense, and the Bible lets us hear every awkward word of it. Here is the honesty of Scripture again, showing us a great man of faith at less than his best, so that we would put our trust not in the greatness of the man but in the faithfulness of his God.

Genesis 20:14-16 (BSB)

¹⁴ So Abimelech brought sheep and cattle, menservants and maidservants, and he gave them to Abraham and restored his wife Sarah to him. ¹⁵ And Abimelech said, “Look, my land is before you. Settle wherever you please.” ¹⁶ And he said to Sarah, “See, I am giving your brother a thousand pieces of silver. It is your vindication before all who are with you; you are completely cleared.”

Now watch the grace of God flow through the hand of a pagan king. Abimelech does not take his revenge, though he easily could. Instead he restores Sarah to Abraham and heaps gifts on him: sheep and cattle, menservants and maidservants, real wealth freely given. Look, he says, my whole land is before you, settle wherever you please. He opens his country to the very man who deceived him. And then, turning to Sarah, he does a gracious and careful thing. He gives a thousand pieces of silver, a great sum, and calls it her vindication, a public sign to everyone around her that she has been wronged by no one and cleared of every shadow. Her honor is protected before all who know her.

Do you see what God is doing here? Abraham did nothing to deserve this. He lied, he was rebuked, he stammered out excuses, and yet he walks away richer and safer than before, with Sarah restored and her name cleared. This is not a reward for good behavior. It is mercy, running downhill toward a man who did not earn it, guarding the wife and the promise through the generosity of a king who owed Abraham nothing. The God who keeps covenant was quietly at work in every gift Abimelech gave.

Genesis 20:17-18 (BSB)

¹⁷ Then Abraham prayed to God, and God healed Abimelech and his wife and his maidservants, so that they could again bear children— ¹⁸ for on account of Abraham’s wife Sarah, the LORD had completely closed all the wombs in Abimelech’s household.

And now the chapter closes exactly where God said it would, with the prophet praying. Then Abraham prayed (פָּלַל) palal, pronounced pah-LAHL. Strong's H6419, to pray, intercede, plead. This is the word for praying in the sense of interceding, of pleading with God on behalf of someone else, of standing in the gap between God and another person and asking Him to act. It is the very thing God had named as the prophet’s work back in the dream, that Abraham would pray and Abimelech would live, and here we watch it happen. What is so tender is who does the praying. The man who wronged this household is the man who now lifts his voice for its healing, and God answers him. This is a small early picture of a great pattern that runs through the whole Bible, of God putting the prayer of intercession into the mouth of an undeserving servant and honoring it, all the way to the one great Intercessor who would pray for those who wronged Him. Thank God that He hears the prayers of forgiven, failing people, and heals through them still. to God, the text says, and God healed Abimelech and his wife and his maidservants, so that they could bear children again. God had shut every womb in the household while Sarah was under that roof, a quiet judgment holding the danger at bay, and now, at the prophet’s prayer, He opens them. The man who caused the trouble becomes the man through whom the healing comes, just as God had promised in the dream. He is a prophet, and he will pray for you, and you will live. And so it happens, word for word.

There is something beautiful and humbling in this ending. Abraham does not restore the household by being impressive. He restores it by praying, by standing between God and these people and asking for mercy, which is the true work God had named him for. And notice the last verse, which the Bible saves for the very end so you will feel it: the LORD had closed the wombs on account of Abraham’s wife Sarah. Even in the middle of Abraham’s failure, God was guarding Sarah, protecting the woman through whom Isaac was about to be born, keeping the promise safe by shutting doors no one could see. Praise the God who is at work in the unseen, guarding what He has sworn to do, even when the one who carries the promise has forgotten to guard it himself.
