Leviticus 19:21
And he shall bring his trespass offering unto the LORD, unto the door of the tabernacle of the congregation, even a ram for a trespass offering. And he shall bring his trespass offering unto the LORD, unto the door of the tabernacle of the congregation, even a ram for a trespass offering.
The voice giving this direction is Jesus Christ Himself, speaking while enshrouded in the cloudy pillar. The instruction was given as a lesson intended for the benefit of future generations, not for that time alone. Its requirement upholds the same high standard found in Christ's teaching in the New Testament. It calls those who have received God's great gift in Jesus to love one another even as Christ has loved them.
