Leviticus 19:18

And Lamech said to his wives, “Adah and Zillah, Hear my voice, You wives of Lamech, Give ear to my word, For I have killed a man for striking me; And a boy for wounding me;

“You shall not bear false witness against your neighbor.

‘The sojourner who sojourns with you shall be to you as the native among you, and you shall love him as yourself, for you were sojourners in the land of Egypt; I am Yahweh your God.

“You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’

Honor your father and mother; and You shall love your neighbor as yourself.”

“And the second is like it, ‘You shall love your neighbor as yourself.’

“The second is this, ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these.”

And he answered and said, “You shall love the Lord your God with all your heart, and with all your soul, and with all your strength, and with all your mind; and your neighbor as yourself.”

“A new commandment I give to you, that you love one another, even as I have loved you, that you also love one another.

For this, “You shall not commit adultery, You shall not murder, You shall not steal, You shall not covet,” and if there is any other commandment, it is summed up in this word, “You shall love your neighbor as yourself.”

For the whole Law is fulfilled in one word, in this: “You shall love your neighbor as yourself.”

If, however, you are fulfilling the royal law according to the Scripture, “You shall love your neighbor as yourself,” you are doing well.

And this commandment we have from Him, that the one who loves God should love his brother also.
