Deuteronomy 6:3

Hear therefore, O Israel, and observe to do it,.... Or them, the commandments given them:

that it may be well with thee; in body and estate:

and that ye may increase mightily; not only in wealth and riches, but chiefly in numbers:

as the Lord God of thy fathers hath promised thee; a promise of increase of numbers was frequently made to Abraham, Isaac, and Jacob; as that their seed should be as the stars of heaven, and as the dust of the earth, and the sand on the sea shore, innumerable; see

Genesis 15:5 and this especially

in the land that floweth with milk and honey; a very common periphrasis of the land of Canaan, because of the plenty of good things in it; see Exodus 3:8.
