Leviticus 19:1-2, 17-18

Then the LORD spoke to Moses, saying: “Speak to all the congregation of the sons of Israel and say to them, ‘You shall be holy, for I the LORD your God am holy.

‘You shall not hate your fellow countryman in your heart; you may surely reprove your neighbor, but shall not incur sin because of him. You shall not take vengeance, nor bear any grudge against the sons of your people, but you shall love your neighbor as yourself; I am the LORD.
