Proverds 10:12 Hatred stirreth up strifes: but love covereth all sins.

Luke 6:35 But love ye your enemies, and do good, and lend, hoping for nothing again; and your reward shall be great, and ye shall be the children of the Highest: for he is kind unto the unthankful and to the evil.

Romans 13:8 Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law. 9For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself. 10Love worketh no ill to his neighbour: therefore love is the fulfilling of the law.
