'Righteous' in the Bible

Pharaoh sent, and called for Moses and Aaron, and said to them, "I have sinned this time. Yahweh is righteous, and I and my people are wicked.

"Keep far from a false charge, and don't kill the innocent and righteous: for I will not justify the wicked.

"You shall take no bribe, for a bribe blinds those who have sight and perverts the words of the righteous.
