Matthew Poole and continuators on Leviticus 3:17

17 It shall be a perpetual statute for your generations, throughout all your dwellings , that ye eat neither fat , nor blood .

Not onely at or near the Tabernacle, nor onely of those beasts which you actually sacrifice, but also in your several dwellings, and of all that kind of beasts.

This was forbidden, 1 To preserve the reverence of the holy rites, and sacrifices. 2. That they might be taught hereby to acknowledge God as their Lord and the Lord of all the creatures, who might reserve what he pleased to himself. 3. To exercise them in obedience to God and self-denial and mortification of their appetites, even in those things which probably many of them would much desire.

This was forbidden partly to maintain reverence to God and his worship; partly out of opposition to Idolaters, who used to drink the blood of their sacrifices; partly with respect unto Christs blood, thereby manifestly signified; and partly for moral admonition about avoiding cruelty, &c.
