Deuteronomy 10:20-22

Thou shalt fear the LORD thy God; him shalt thou serve, and to him shalt thou cleave, and swear by his name. He is thy praise, and he is thy God, that hath done for thee these great and terrible things, which thine eyes have seen. Thy fathers went down into Egypt with threescore and ten persons; and now the LORD thy God hath made thee as the stars of heaven for multitude.
