12 The Lord will open to you his good treasury the heavens, to give the rain of your land in its season and to bless all the work of your hands; and you shall lend to many nations, but you shall not borrow. 13 And the Lord will make you the head, and not the tail; and you shall tend upward only, and not downward; if you obey the commandments of the Lord your God, which I command you this day, being careful to do them,
Matthew Henry's Commentary on Deuteronomy 28:12-13
Commentary on Deuteronomy 28:1-14
(Read Deuteronomy 28:1-14)
This chapter is a very large exposition of two words, the blessing and the curse. They are real things and have real effects. The blessings are here put before the curses. God is slow to anger, but swift to show mercy. It is his delight to bless. It is better that we should be drawn to what is good by a child-like hope of God's favour, than that we be frightened to it by a slavish fear of his wrath. The blessing is promised, upon condition that they diligently hearken to the voice of God. Let them keep up religion, the form and power of it, in their families and nation, then the providence of God would prosper all their outward concerns.
