Deuteronomy 28:13-14

The LORD will make you the head (leader) and not the tail (follower); and you will be above only, and you will not be beneath, if you listen and pay attention to the commandments of the LORD your God, which I am commanding you today, to observe them carefully. Do not turn aside from any of the words which I am commanding you today, to the right or to the left, to follow and serve other gods.
