Deuteronomy 28:13-14

13And Jehovah will make thee the head, and not the tail; and thou shalt be above only, and thou shalt not be beneath; if thou hearken unto the commandments of Jehovah thy 1God, which I command thee this day, to keep and to do them,

14and if thou turn not aside from any of the words that I command thee this day, to the right hand or to the left, to go after other 2gods to serve them.
