Deuteronomy 31:27

27 For I know well how rebellious and stubborn you are. If you already have been so rebellious toward the Lord while I am still alive among you, how much more after my death!

Deuteronomy 31:27 In-Context

25 Moses commanded the Levites who carried the ark of the covenant of the Lord, saying,
26 "Take this book of the law and put it beside the ark of the covenant of the Lord your God; let it remain there as a witness against you.
27 For I know well how rebellious and stubborn you are. If you already have been so rebellious toward the Lord while I am still alive among you, how much more after my death!
28 Assemble to me all the elders of your tribes and your officials, so that I may recite these words in their hearing and call heaven and earth to witness against them.
29 For I know that after my death you will surely act corruptly, turning aside from the way that I have commanded you. In time to come trouble will befall you, because you will do what is evil in the sight of the Lord, provoking him to anger through the work of your hands."
