Matthew Poole and continuators on Leviticus 1:5

5 And he shall kill the bullock before the LORD: and the Priests, Aarons sons shall bring the bloud, and sprinkle the blood round about upon the Altar that is by the door of the Tabernacle of the Congregation.

Either 1. the offerer, who is said to do it, to wit, by the Priest: for men are commonly said to do what they cause others to do, as Ioh. 4. 1, 2. Or 2. the Priest, as it follows, or the Levite, whose office this was. See Exod. 29. 11. Levit. 8. 15. Numb. 8. 19. 1 Chron. 23. 28, 31. 2 Chron. 30. 16. and 35▪ 11.

Which was done in a considerable quantity, as may be gathered from Zech. 9. 15. and whereby was signified, 1. that the offerer deserved to have his blood spilt in that manner. 2. that the blood of Christ should be poured forth for sinners, and that that was the onely mean of their reconciliation to God and acceptance with him.
