Deuteronomy 28:13-14
Context28:13 The Lord will make you the head and not the tail, and you will always end up at the top and not at the bottom, if you obey his 1 commandments which I am urging 2 you today to be careful to do. 28:14 But you must not turn away from all the commandments I am giving 3 you today, to either the right or left, nor pursue other gods and worship 4 them.
