It is a sweet lesson, spiritually considered, which the LORD'S people may read here. Mount Seir is a type of the earth, and all its carnal pursuits and pleasures. These hath the LORD given to the children of men. David saith, that the men of the world have their portion in this life, it is all they seek; and all they desire. Psalms 17:14. In the common and necessary wants of life, the people of GOD are permitted to buy of them what they need, but no more. In all other matters that precept of the apostle holds good, and the observance of it carries with it its own reward; see 2 Corinthians 6:17-18.
Deuteronomy 2:2-6
2 And the LORD spake unto me, saying,
3 Ye have compassed this mountain long enough: turn you northward.
4 And command thou the people, saying, Ye are to pass through the coast of your brethren the children of Esau, which dwell in Seir; and they shall be afraid of you: take ye good heed unto yourselves therefore:
5 Meddle not with them; for I will not givea you of their land, no, not so much as a foot breadth; because I have given mount Seir unto Esau for a possession.
6 Ye shall buy meat of them for money, that ye may eat; and ye shall also buy water of them for money, that ye may drink.
