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 Otherwise, the avenger of blood in the heat of his anger might pursue the one who committed manslaughter, overtake him because the distance is great, and strike him dead. Yet he did not deserve to die, since he did not previously hate his neighbor.

7 This is why I am commanding you to set apart three cities for yourselves.

8 If the Lord your God enlarges your territory as He swore to your fathers, and gives you all the land He promised to give them-

9 provided you keep every one of these commands I am giving you today and follow them, loving the Lord your God and walking in His ways at all times-you are to add three more cities to these three.

10 In this way, innocent blood will not be shed, and you will not become guilty of bloodshed in the land the Lord your God is giving you as an inheritance.
