Deuteronomy 31:16, 29

The LORD said to Moses, “Behold, you are about to lie down [in death] with your fathers; and this people will arise and play the prostitute (commit apostasy) with the foreign gods [of the people] of the land, where they go to be among them. They will abandon (turn away from) Me and break My covenant which I have made with them.

For I know that after my death you will behave corruptly and turn from the way which I have commanded you; and evil will come upon you in the latter days, because you will do evil in the sight of the LORD, provoking Him to anger with the work of your hands.”
