Deuteronomy 31:16 is God’s warning to Moses that, after Moses dies, the Israelites will turn away from the LORD to worship the gods of the surrounding nations, breaking the covenant he made with them. It is a prediction of future unfaithfulness, not a command, and it explains why God was about to speak to the people through a song. The LORD speaks these words directly to Moses, at the Tent of Meeting, in the moment before Moses hands leadership to Joshua.
The LORD said to Moses, “Behold, you shall sleep with your fathers. This people will rise up, and play the prostitute after the strange gods of the land, where they go to be among them, and will forsake me, and break my covenant which I have made with them.

What Deuteronomy 31:16 Means
The verse begins with a plain statement of mortality: “you shall sleep with your fathers” is an old idiom for dying and being buried with one’s ancestors. God is not being harsh here. He is naming a fact so that Moses understands what comes next. The people will not remain faithful once their great leader is gone.
The language of “play the prostitute” is the prophetic image of spiritual adultery, a picture used throughout the Old Testament to describe Israel chasing other gods while claiming to belong to the LORD. The phrase “where they go to be among them” shows that the danger is social as much as religious: the people will settle among Canaanite neighbors and adopt their customs. The verse ends with the core grief of the passage, that the people “will forsake me, and break my covenant.”
What the verse does not do is promise doom as the final word. It describes what the people will do, not what God will ultimately do with them. The surrounding chapter pairs this warning with a song meant to remind Israel of its own failure and of God’s faithfulness, so the warning functions as a call to remember.
The Context of Deuteronomy 31:16
Deuteronomy presents itself as a series of speeches Moses gives to Israel on the plains of Moab, just before they cross the Jordan into the land God promised their ancestors. Tradition attributes the book to Moses, and it is addressed to the generation that will enter Canaan, while the older generation that left Egypt has largely died in the wilderness. Chapter 31 is the moment of transition, when Moses is nearing death and Joshua is being commissioned to lead.
Verses 13 through 19 show the verse in its setting. Moses has just urged the people to teach their children to fear the LORD, and God then tells Moses that his death is near. The warning in verse 16 is immediately followed by God’s statement that his anger will burn against the people and that he will hide his face from them. Read this way, verse 16 is less a prophecy of despair than the reason the song in verse 19 is needed: Israel must have words in its mouth that will testify against its own drift.
Key Phrases in Deuteronomy 31:16
Deuteronomy 31:19
“Now therefore write this song for yourselves, and teach it to the children of Israel. Put it in their mouths, that this song may be a witness for me against the children of Israel.

Verse 19 completes the thought of verse 16 by telling Moses to write a song that will stand as a witness against Israel. The same chapter that warns of unfaithfulness also provides the means to keep the people’s memory of God alive, which shows that God’s warning comes with a remedy already in hand.
Joshua 24:15
If it seems evil to you to serve the LORD, choose today whom you will serve; whether the gods which your fathers served that were beyond the River, or the gods of the Amorites, in whose land you dwell; but as for me and my house, we will serve the LORD.”

Joshua’s farewell speech shows a later generation facing the very choice Moses foresaw. Joshua calls Israel to decide whom they will serve, which turns the warning of verse 16 into a living question that each generation must answer again.
A Short Prayer From Deuteronomy 31:16
Lord, you knew the hearts of your people before they had crossed the Jordan, and still you did not stop speaking to them. Keep my own heart from drifting toward the many voices that promise more than you do. Where I have already wandered, bring me back gently, and let the words you have given me become a witness that holds me steady. Thank you for being faithful even when I am not. Amen.
