Leviticus 19:1-2, 17-18

And 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 hate your brother in your heart, but you shall reason frankly with your neighbor, lest you incur sin because of him. You shall not take vengeance or bear a grudge against the sons of your own people, but you shall love your neighbor as yourself: I am the LORD.
