that you may be sons of your Father who is in heaven; for He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.… Therefore you are to be perfect, as your heavenly Father is perfect.” Jesus’ words “You shall love your neighbor” are a quotation from Leviticus 19:18—words that come directly after a prohibition against revenge or a personal grudge, and that are considered the second greatest commandment by Jesus’ own testimony (Matt. 22:39; Mark 12:31).
