Leviticus 19:15-18

You shall not render an unjust judgment; you shall not be partial to the poor or defer to the great: with justice you shall judge your neighbor. You shall not go around as a slanderer among your people, and you shall not profit by the blood of your neighbor: I am the LORD. You shall not hate in your heart anyone of your kin; you shall reprove your neighbor, or you will incur guilt yourself. You shall not take vengeance or bear a grudge against any of your people, but you shall love your neighbor as yourself: I am the LORD.
