'Do Not Forget' in the Bible

Be on guard so that you do not forget the covenant of the Lord your God that he has made with you, and that you do not make an image of any kind, just as he has forbidden you.

Be sure you do not forget the Lord your God by not keeping his commandments, ordinances, and statutes that I am giving you today.

So when the Lord your God gives you relief from all the enemies who surround you in the land he is giving you as an inheritance, you must wipe out the memory of the Amalekites from under heaven -- do not forget!
