Deuteronomy 6:4-9
4 “Hear, O Israel: The Lord our God, the Lord is one! 5 You shall love the Lord your God with all your heart, with all your soul, and with all your strength.

6 “And these words which I command you today shall be in your heart. 7 You shall teach them diligently to your children, and shall talk of them when you sit in your house, when you walk by the way, when you lie down, and when you rise up. 8 You shall bind them as a sign on your hand, and they shall be as frontlets between your eyes. 9 You shall write them on the doorposts of your house and on your gates.

Matthew 22:37-40
37 Jesus said to him, “‘You shall love the Lord your God with all your heart, with all your soul, and with all your mind.’ 38 This is the first and great commandment. 39 And the second is like it: ‘You shall love your neighbor as yourself.’ 40 On these two commandments hang all the Law and the Prophets.”

Leviticus 19:17-18
17 ‘You shall not hate your brother in your heart. You shall surely rebuke your neighbor, and not bear sin because of him. 18 You shall not take vengeance, nor bear any grudge against the children of your people, but you shall love your neighbor as yourself: I am the Lord.

Matthew 5:21-26
21 “You have heard that it was said to those of old, ‘You shall not murder, and whoever murders will be in danger of the judgment.’ 22 But I say to you that whoever is angry with his brother without a cause shall be in danger of the judgment. And whoever says to his brother, ‘Raca!’ shall be in danger of the council. But whoever says, ‘You fool!’ shall be in danger of hell fire. 23 Therefore if you bring your gift to the altar, and there remember that your brother has something against you, 24 leave your gift there before the altar, and go your way. First be reconciled to your brother, and then come and offer your gift. 25 Agree with your adversary quickly, while you are on the way with him, lest your adversary deliver you to the judge, the judge hand you over to the officer, and you be thrown into prison. 26 Assuredly, I say to you, you will by no means get out of there till you have paid the last penny.

Galatians 5:22-23
22 But the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness, 23 gentleness, self-control. Against such there is no law.
