The Lord God of your fathers make you a thousand times so many more as ye are,.... This prayer he made, or this blessing he pronounced on them, to show that he did not envy their increase, nor was any ways uneasy at it, but rejoiced in it, though he gave it as a reason of his not being able to govern them alone:
and bless you, as he hath promised you: with all kind of blessings, as he had often promised their fathers.
But in order to guard against any misinterpretation of his words, "I cannot bear you myself alone," Moses added, "May the Lord fulfil the promise of numerous increase to the nation a thousand-fold." "Jehovah, the God of your fathers (i.e., who manifested Himself as God to your fathers), add to you a thousand times, כּכם, as many as ye are, and bless you as He has said." The "blessing" after "multiplying" points back to Genesis 12:2. Consequently, it is not to be restricted to "strengthening, rendering fruitful, and multiplying," but must be understood as including the spiritual blessing promised to Abraham.
