'Forget Not' in the Bible

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 from the land of Egypt, until ye came to this place, ye have been rebellious against the LORD.
