3B The red heifer was without defect; this signifies that although Christ was in the likeness of the flesh of sin, He did not have the sinful nature—v. 14; Heb. 2:14; 4:15; Rom. 8:3; 2 Cor. 5:21.
5D The heifer having never been under a yoke signifies that Christ was never used by anyone, especially by or for God's enemy, Satan—Num. 19:2; cf. Exo. 12:5.
6E The red heifer was brought outside the camp and slaughtered; Christ was crucified outside the camp, on Calvary, a small mount outside the city of Jerusalem—Num. 19:3; Heb. 13:12-13; Matt. 27:33.
