'Righteous' in the Bible

And Pharaoh sent, and called for Moses and Aaron, and said unto them, I have sinned this time: the LORD is righteous, and I and my people are wicked.

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.
