Numbers 15:20 (c) The lifting and moving back and forth of the sacrifices of the Israelites was called heaving. It represents the Christian holding up before the Lord figuratively and waving back and forth before His face the beauty and loveliness of CHRIST, the Blood of CHRIST, the sacrifice of the Saviour, so that he calls attention to the virtues of His Son, rather than to any merits of his own, (See also Numbers 18:19).
