'Forget Not' in the Bible

Only take thou heed to thyself and keep thy soul diligently, so that thou forget not the things which thine own eyes have seen, and so that they go not out of thy heart, all the days of thy life, - but thou shalt make them known unto thy sons and unto thy son's sons: -

Take heed unto yourselves therefore, that ye forget not the covenant of the LORD your God which he made with you, and that ye make you no graven image of whatsoever it be that the LORD thy God hath forbidden thee.

Beware that thou forget not the LORD thy God, in not keeping his commandments, and his judgments, and his statutes, which I command thee this day:

Remember, and forget not, how thou provokedst the LORD thy God to wrath in the wilderness: from the day that thou didst depart out of the land of Egypt, until ye came unto this place, ye have been rebellious against the LORD.

Therefore when the LORD thy God hath given thee rest from all thine enemies round about, in the land which the LORD thy God giveth thee to inherit and possess: see that thou put out the name of Amalek from under heaven, and forget not.
