Deuteronomy 28:14

Deu 28:14 And thou shalt not go aside from any of the words which I command thee this day, [to] the right hand, or [to] the left, to go after other gods to serve them.

Ver. 14. And thou shalt not go aside. ] But keep my commandments curiously, even "as the apple of thine eye," Pro 7:2 with all chariness and circumspection, since the least deviation is dangerous, yea, destructive.
