Galatians 5:14
In fact, the whole law has been fulfilled in one word, even in this: “You will love your neighbor as yourself.”
Romans 13:8-10
Owe nothing to anyone, except to love one another, for he who loves another has fulfilled the law. For example: “You will not commit adultery, you will not murder, you will not steal, you will not covet,” and if there is any other commandment, it is summed up [under one heading] in this word, namely, “You will love your neighbor as yourself.” Love does not work evil to the neighbor. Therefore, love is the fulfillment of the law.
