'Forgotten' in the Bible

My people are destroyed for lack of knowledge: because thou hast rejected knowledge, I will also reject thee, that thou shalt be no priest to me: seeing thou hast forgotten the law of thy God, I will also forget thy children.

For Israel hath forgotten his Maker, and buildeth temples; and Judah hath multiplied fenced cities: but I will send a fire upon his cities, and it shall devour the palaces thereof.

According to their pasture, so were they filled; they were filled, and their heart was exalted; therefore have they forgotten me.
