Deuteronomy 28:12-14

The 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. And 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. So you shall not turn aside from any of the words which I command you this day, to the right or the left, to go after other gods to serve them.
