Exodus 23:22

Brenton(i) 22 If ye will indeed hear my voice, and if thou wilt do all the things I shall charge thee with, and keep my covenant, ye shall be to me a peculiar people above all nations, for the whole earth is mine; and ye shall be to me a royal priesthood, and a holy nation: these words shall ye speak to the children of Israel, If ye shall indeed hear my voice, and do all the things I shall tell thee, I will be an enemy to thine enemies, and an adversary to thine adversaries.
