'Forgotten' in the Bible

You shall say before Yahweh your God, "I have put away the holy things out of my house, and also have given them to the Levite, and to the foreigner, to the fatherless, and to the widow, according to all your commandment which you have commanded me: I have not transgressed any of your commandments, neither have I forgotten them:

It shall happen, when many evils and troubles are come on them, that this song shall testify before them as a witness; for it shall not be forgotten out of the mouths of their seed: for I know their imagination which they frame this day, before I have brought them into the land which I swore."

Of the Rock who became your father, you are unmindful, and have forgotten God who gave you birth.
