Leviticus 10:18

Behold, the blood of it was not brought in within the Holy Place, to the altar of incense, as it was described Leviticus 4:1; ye should indeed have eaten it in the Holy Place, as I commanded. Having undertaken the atonement for the people, the responsibility for the sins and that of carrying out every single precept of the sacrifice rested upon them.

Thou shalt not avenge, seek and take revenge for a wrong which has been inflicted, nor bear any grudge against the children of thy people, Romans 12:19, after a wrong has been committed, but thou shalt love thy neighbor as thyself. I am the Lord. Cf Matthew 19:19; Matthew 22:39. Many of these cases, if not all, are applications of the law of love, and therefore require to be observed by Christians to this day.
