John Wesley on Leviticus 19:17

Thou shalt not hate - As thou dost, in effect, if thou dost not rebuke him. Thy brother - The same as thy neighbour, that is, every man. If thy brother hath done wrong, thou shalt neither divulge it to others, nor hate him, and smother that hatred by sullen silence; nor flatter him therein, but shalt freely and in love, tell him of his fault. And not suffer sin upon him - Not suffer him to lie under the guilt of any sin, which thou by rebuking him, and thereby bringing him to repentance, couldst free him from.
