Leviticus 1:5

5. Shall kill After the most searching scrutiny by the priest, if the animal was pronounced perfect, the offerer killed it, except when it was presented in behalf of the whole congregation; then it was killed by the high priest. Chap. Leviticus 16:15.

The bullock Literally, the son of a bull. The term ox is often used in a broad sense as describing sacrificial victims of the bovine genus, but in the narrow sense of modern parlance it is an improper term, since the ox is not a perfect male. See note on Leviticus 1:3.

Before the Lord Since Jehovah had deigned to take up his abode between the cherubim above the mercy seat in the holy of holies, the whole tabernacle, recently illumined with his glory, was filled with his special presence. Hence before the open door of the holy place, the court of the priests, was before the Lord.

The priests, Aaron’s sons They had been designated (Exodus xxix) but not yet consecrated. Chap. 8.

Sprinkle the blood Brought from the door of the tabernacle to the altar, it is to be copiously spilled upon the ground round about, upon the altar’s walls, and probably upon its top. The verb sprinkle here used is different from that employed to express the scattering of drops with the finger or hyssop. As no instrument for sprinkling is here specified, and as the same verb is used when all the blood of an ox, as here, and all the blood of a sheep, Leviticus 1:11, are to be thus treated, we infer that the manner was by waving the basin and spilling the blood. For the ceremonial office of the blood see Introduction, (6.)
