Deuteronomy 28:12-13

12The Lord will open to you His good treasure, the heavens, to give the rain to your land in its season, and to bless all the work of your hand. You shall lend to many nations, but you shall not borrow.

13And the Lord will make you the head and not the tail; you shall be above only, and not be beneath, if you heed the commandments of the Lord your God, which I command you today, and are careful to observe them.
