Deuteronomy 19:8 Meaning and Commentary

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 1 Kings 4:24 ) . 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 ) ( Genesis 26:3 Genesis 26:4 ) ( Genesis 28:13 Genesis 28:14 ) .

Deuteronomy 19:8 In-Context

6 lest the avenger of blood pursue the manslayer, while his heart is hot, and overtake him, because the way is long, and strike him mortally; whereas he was not worthy of death, inasmuch as he didn't hate him in time past.

7 Therefore I command you, saying, You shall set apart three cities for you.

8 If Yahweh your God enlarge your border, as he has sworn to your fathers, and give you all the land which he promised to give to your fathers;

9 if you shall keep all this commandment to do it, which I command you this day, to love Yahweh your God, and to walk ever in his ways; then shall you add three cities more for you, besides these three:

10 that innocent blood not be shed in the midst of your land, which Yahweh your God gives you for an inheritance, and so blood be on you.
