'Forgotten' in the Bible

'And thy heart hath been high, and thou hast forgotten Jehovah thy God (who is bringing thee out of the land of Egypt, out of a house of servants;

'When thou reapest thy harvest in thy field, and hast forgotten a sheaf in a field, thou dost not turn back to take it; to the sojourner, to the fatherless, and to the widow, it is; so that Jehovah thy God doth bless thee in all the work of thy hands.

Then thou shalt say before the LORD thy God, I have brought away the hallowed things out of mine house, and also have given them unto the Levite, and unto the stranger, to the fatherless, and to the widow, according to all thy commandments which thou hast commanded me: I have not transgressed thy commandments, neither have I forgotten them:

"I've removed the holy offering from my house and given it to the descendants of Levi, to the foreigners, to the orphans, and to the widows just as you have commanded me. I haven't violated or forgotten your commands. I haven't eaten any part of it while mourning, nor removed any part of it while unclean, nor offered any of it to the dead. I've obeyed the voice of the LORD my God and did all that he commanded me.

And it shall come to pass, when many evils and troubles are befallen them, that this song shall testify against them as a witness; for it shall not be forgotten out of the mouths of their seed: for I know their imagination which they go about, even now, before I have brought them into the land which I sware.

Of the Rock that begat thee thou art unmindful, and hast forgotten God that formed thee.
