Charles Ellicott Commentary Deuteronomy 1:11

"Jehovah, the God of your fathers, make you a thousand times as many as ye are, and bless you, as he hath promised you!" — Deuteronomy 1:11 (ASV)

The Lord God of your fathers ... bless you. — This appears to belong distinctly to the Book of Deuteronomy. It can hardly be a record of what was spoken long before. It brings the living speaker before us in a way that precludes imitation.
