Exodus 32:13

Remember Abraham, Isaac, and Israel, Thy servants, to whom Thou swarest by Thine own self, and saidst unto them, I will multiply your seed as the stars of heaven, and all this land that I have spoken of will I give unto your seed, and they shall inherit; it forever. This was a reminder of the faithfulness and truth, the trust in which had sustained the patriarchs during the long years when they were strangers in the land of Canaan. Note also that Moses omits all reference to himself; he does not think of urging his own work as a consideration to influence the Lord.
