Leviticus 19:1-2, 15-18
The Lord spoke to Moses, saying: Speak to all the congregation of the people of Israel and say to them: You shall be holy, for I the Lord your God am holy. 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.
