Deuteronomy 8:11; Deuteronomy 8:14; Deuteronomy 8:19

11 "Beware that you do not forget the LORD your God by not keeping His commandments and His ordinances and His statutes which I am commanding you today;

14 then your heart will become proud and you will forget the LORD your God who brought you out from the land of Egypt, out of the house of slavery.

19 "It shall come about if you ever forget the LORD your God and go after other gods and serve them and worship them, I testify against you today that you will surely perish.
