28:12 The LORD shall open unto thee his good treasure, the {i} heaven to give the rain unto thy land in his season, and to bless all the work of thine hand: and thou shalt lend unto many nations, and thou shalt not borrow.
(i) For nothing in the earth is profitable but when God sends his blessings from heaven.
28:12 His treasure - The heaven or the air, which is God's storehouse, where he treasures up rain or wind for man's use.
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.
