'Forgotten' in the Bible

and thou shalt say before Jehovah thy God, I have brought away the hallowed things out of the house, and also have given them to the Levite, and to the stranger, to the fatherless, and to the widow, according to all thy commandment which thou hast commanded me; I have not transgressed nor forgotten any of thy commandments:

And it shall come to pass, when many evils and troubles have 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 are forming already this day, before I bring them into the land which I have sworn unto them.

Of the Rock that begot thee wast thou unmindful, And thou hast forgotten God who brought thee forth.
