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 in hot anger pursue the manslayer and overtake him, because the way is long, and wound him mortally, though the man did not deserve to die, since he was not at enmity with his neighbor in time past.
7 Therefore I command you, You shall set apart three cities.
8 And if the LORD your God enlarges your border, as he has sworn to your fathers, and gives you all the land which he promised to give to your fathers--
9 provided you are careful to keep all this commandment, which I command you this day, by loving the LORD your God and by walking ever in his ways--then you shall add three other cities to these three,
10 lest innocent blood be shed in your land which the LORD your God gives you for an inheritance, and so the guilt of bloodshed be upon you.
