Exodus 23:6-9

Thou shalt not wrest the judgment of thy poor in his cause. Keep thee far from a false matter; and the innocent and righteous slay thou not: for I will not justify the wicked. And thou shalt take no gift: for the gift blindeth the wise, and perverteth the words of the righteous. Also thou shalt not oppress a stranger: for ye know the heart of a stranger, seeing ye were strangers in the land of Egypt.
