Leviticus 1:5 - Coke's Commentary on the Holy Bible

And the priests—shall bring the blood— This blood, as Le Clerc observes, was to be offered by the priest alone, and served to remind the person who brought the victim, that he was in a sinful state, and so not worthy to have access to God, but through a mediator; and a mediator, be it noted, offering the blood of the sacrifice. The heathens had the same custom: they received the blood of the sacrifices in vessels prepared for that purpose, and then offered it to their deities by pouring it upon the altar. The reader will find, in Homer's Iliad, a very accurate account of their manner of sacrifice; which was evidently borrowed from the ceremonials of the true religion before, the coming of the great Antitype.
