So watch yourselves, that you do not forget the covenant of the LORD your God which He made with you, and make for yourselves a graven image in the form of anything against which the LORD your God has commanded you. (Deut. 4:23 NASB) The idea here is that the Israelites would intentionally ignore their covenant, not necessarily forget that they made it. When the Israelites lapse into idolatry, we also hear God threatening to “forget” them: Therefore behold, I will surely forget you and cast you away from My presence, along with the city which I gave you and your fathers. (Jer. 23:39 NASB)
