Deuteronomy 19:8

And if the Lord thy God enlarge thy coast ,.... Extend it further than it was upon their first settlement, even carry it as far as the river Euphrates, as in the times of Solomon, 1 Kings 4:21 . Jarchi interprets it of such an enlargement as to give them the land of the Kenites, the Kenizzites and Kadmonites:

(as he hath sworn unto thy fathers), and give thee all the land which he promised to give unto thy, fathers : Abraham, Isaac, and Jacob; see Genesis 15:19 .
