'Do Not Forget' in the Bible

"However, {take care} for yourself and watch your inner self closely, so that you do not forget the things that your eyes have seen, so that they do not slip from your mind all the days of your life; and you shall make them known to your children and to {your grandchildren}.

Watch [out] for yourselves so that you do not forget the covenant of Yahweh your God that he had {made} with you and make for yourselves a divine image [of] the form of anything that Yahweh your God {has forbidden},

Remember, {do not forget}, that you provoked Yahweh your God in the desert, [and] from the day that you went out from the land of Egypt until {you came to this place} you were rebelling against Yahweh.
