'Forget' in the Bible

Cut off have been My people for lack of knowledge, Because thou knowledge hast rejected, I reject thee from being priest to Me, And thou forgettest the law of thy God, I forget thy sons, I also!

And forget doth Israel his Maker, and buildeth temples, And Judah hath multiplied cities of defence, And I have sent a fire into his cities, And it hath consumed their palaces!
