Deuteronomy 29

Today’s Passage: Deuteronomy 29

Moses gathers all Israel in the plains of Moab to enter the covenant afresh, a covenant made here in addition to the one at Horeb. He reminds them that their own eyes watched everything the LORD did in Egypt and in the wilderness, that their clothes and sandals never wore out across forty years, and yet that only now is the LORD giving them a heart to understand it. He binds the covenant not only to those standing there but to every generation still to come. He warns that a single hidden root of idolatry can poison the whole people and bring ruin like the overthrow of Sodom. And he closes with one of the great sentences of Scripture: the secret things belong to the LORD, but the things revealed belong to us and to our children forever, so that we may keep this law.

As you read, hold this: Much about God stays hidden in Him, but what He has plainly revealed in His word is enough for His people to know Him and walk with Him.

Deuteronomy 29:1–4 (BSB)

¹ These are the words of the covenant that the LORD commanded Moses to make with the Israelites in the land of Moab, in addition to the covenant He had made with them at Horeb. ² Moses summoned all Israel and proclaimed to them, “You have seen with your own eyes everything the LORD did in Egypt to Pharaoh, to all his officials, and to all his land. ³ You saw with your own eyes the great trials, and those miraculous signs and wonders. ⁴ Yet to this day the LORD has not given you a mind to understand, eyes to see, or ears to hear.

Moses begins with what they have seen, and he says it twice: with your own eyes. No one in that assembly heard this secondhand. They watched the plagues fall on Egypt, they walked through the sea, they were fed and led for forty years. And then comes a sobering word. For all they have seen, the LORD has not yet given them the deeper thing, a mind that truly understands, eyes that truly see, ears that truly hear. Seeing the wonders was not the same as grasping them. The heart that receives the truth is itself a gift, and Moses tells them plainly that it is a gift the LORD had not, until now, given.

Deuteronomy 29:5–9 (BSB)

⁵ For forty years I led you in the wilderness, yet your clothes and sandals did not wear out. ⁶ You ate no bread and drank no wine or strong drink, so that you might know that I am the LORD your God. ⁷ When you reached this place, Sihon king of Heshbon and Og king of Bashan came out against us in battle, but we defeated them. ⁸ We took their land and gave it as an inheritance to the Reubenites, the Gadites, and the half-tribe of Manasseh. ⁹ So keep and follow the words of this covenant, that you may prosper in all you do.

Here Moses points to the quiet, steady wonders, the ones a person could easily overlook. For forty years in a wilderness that should have worn them to nothing, their clothes and their sandals did not wear out. They ate no ordinary bread and drank no wine, and were kept alive by the hand of God, so that they might know one thing: that He is the LORD their God. Then the recent victories over Sihon and Og, and the land already given to the tribes who would settle east of the Jordan. All of it leads to a single command in verse nine: so keep and follow the words of this covenant. The remembered mercies are the ground of the obedience He asks.

Deuteronomy 29:10–15 (BSB)

¹⁰ All of you are standing today before the LORD your God—you leaders of tribes, elders, officials, and all the men of Israel, ¹¹ your children and wives, and the foreigners in your camps who cut your wood and draw your water— ¹² so that you may enter into the covenant of the LORD your God, which He is making with you today, and into His oath, ¹³ and so that He may establish you today as His people, and He may be your God as He promised you and as He swore to your fathers, to Abraham, Isaac, and Jacob. ¹⁴ I am making this covenant and this oath not only with you, ¹⁵ but also with those who are standing here with us today in the presence of the LORD our God, as well as with those who are not here today.

Notice who is gathered. Not only the leaders and elders and fighting men, but the children, the wives, and even the foreigners in the camp who cut the wood and draw the water. The whole community, high and low, stands together to enter the covenant, so that the LORD may establish them as His people and be their God, keeping the ancient promise sworn to Abraham, Isaac, and Jacob. Then Moses widens the circle further still. This oath is made not only with those present, but with those who are not here today, the generations still to come. The covenant reaches past the people standing in Moab and binds their children and their children’s children. What is sworn on this day belongs to households not yet born.

Deuteronomy 29:16–21 (BSB)

¹⁶ For you yourselves know how we lived in the land of Egypt and how we passed through the nations on the way here. ¹⁷ You saw the abominations and idols among them made of wood and stone, of silver and gold. ¹⁸ Make sure there is no man or woman, clan or tribe among you today whose heart turns away from the LORD our God to go and worship the gods of those nations. Make sure there is no root among you that bears such poisonous and bitter fruit, ¹⁹ because when such a person hears the words of this oath, he invokes a blessing on himself, saying, ‘I will have peace, even though I walk in the stubbornness of my own heart.’ This will bring disaster on the watered land as well as the dry. ²⁰ The LORD will never be willing to forgive him. Instead, His anger and jealousy will burn against that man, and every curse written in this book will fall upon him. The LORD will blot out his name from under heaven ²¹ and single him out from all the tribes of Israel for disaster, according to all the curses of the covenant written in this Book of the Law.

Now Moses names the danger, and it is not an invading army but a hidden thing inside the camp. They have seen the idols of Egypt and the nations, gods of wood and stone and silver and gold, and the warning is that no one among them, no single man or woman, no clan or tribe, should carry a heart that quietly turns away to serve them. He calls such a person a root that bears poisonous and bitter fruit. The picture is exact. A root grows unseen, underground, while the poison it produces spreads. And the most dangerous form of it is the one who hears the covenant oath and then blesses himself in his own mind, telling himself he will have peace even while he walks in the stubbornness of his heart. He treats hidden rebellion as though it were safe. Moses says it is not. Secret turning does not stay contained; it brings disaster on the watered land and the dry alike. What a person hides in the heart, God sees, and it works its ruin.

Deuteronomy 29:22–28 (BSB)

²² Then the generation to come—your sons who follow you and the foreigner who comes from a distant land—will see the plagues of the land and the sicknesses the LORD has inflicted on it. ²³ All its soil will be a burning waste of sulfur and salt, unsown and unproductive, with no plant growing on it, just like the destruction of Sodom and Gomorrah, Admah and Zeboiim, which the LORD overthrew in His fierce anger. ²⁴ So all the nations will ask, ‘Why has the LORD done such a thing to this land? Why this great outburst of anger?’ ²⁵ And the people will answer, ‘It is because they abandoned the covenant of the LORD, the God of their fathers, which He made with them when He brought them out of the land of Egypt. ²⁶ They went and served other gods, and they worshiped gods they had not known—gods that the LORD had not given to them. ²⁷ Therefore the anger of the LORD burned against this land, and He brought upon it every curse written in this book. ²⁸ The LORD uprooted them from their land in His anger, rage, and great wrath, and He cast them into another land, where they are today.’

Moses lets them see the far end of the road that hidden idolatry travels. A later generation, and even strangers from distant lands, will look on a ruined country, its soil a burning waste of sulfur and salt where nothing grows, and they will compare it to the overthrow of Sodom and Gomorrah. And they will ask why. The answer given is plain and sober: because the people abandoned the covenant of the LORD and served gods they had not known. The private root, left to grow, does not stay private. It ends in a land laid bare and a people uprooted and scattered. Moses sets this warning before them not to crush their hope but to show them, before they cross, exactly what is at stake in a heart that turns away.

Deuteronomy 29:29 (BSB)

²⁹ The secret things belong to the LORD our God, but the things revealed belong to us and to our children forever, so that we may follow all the words of this law.

And then, after all the weight of the warning, comes one of the most steadying sentences in all of Scripture. There are secret things, and they belong to the LORD our God. Why He works as He does, what lies ahead, the hidden reasons folded into His purposes, all of this remains His, and it is right that it should. We are not given to know it, and we do not need to. But the things revealed, the covenant, the commandments, the character of God set down in His word, these belong to us and to our children forever. Notice the reason at the end of the verse: so that we may follow all the words of this law. God has not told His people everything, but He has told them enough. What He has plainly made known is fully sufficient for a life of faithful obedience. The believer is not left to chase after hidden knowledge; the believer is given a revealed word and called to walk by it.
