20 When the Lord has given security to the rest of the Israelites, as he has to you, and when they occupy the land the Lord your God is giving them across the Jordan River, then you may all return here to the land I have given you.'

Matthew Henry's Commentary on Deuteronomy 3:20

Commentary on Deuteronomy 3:12-20

(Read Deuteronomy 3:12-20)

When at rest, we should desire to see our brethren at rest too, and should be ready to do what we can towards it; for we are not born for ourselves, but are members one of another.
