Leviticus 7:26, Not eat any blood. YHVH revealed in the Torah that the life of flesh is in the blood (Lev 17:11). Therefore, the blood symbolizes the whole life of the living being. This is why the blood being poured upon the altar made atonement for the souls of men (Lev 17:11–12), since it represented and pointed to the shedding of Yeshua’s blood when he sacrificed his life on the cross in atoning for men’s sins. Respecting the blood is necessary not only because it symbolizes the sanctity of the life of man who was made in the Creator’s image (Gen 1:26 cp. 9:6), but more importantly, because of the blood of Elohim’s Son that was shed for man’s redemption (Lev 17:11). For one to eat the blood showed disdain for what the blood typifies. In times past, this was so important to YHVH that a violation of this prohibition resulted in banishment from the nation of Israel.
The blood was to be reserved for the sacrificial service, where it was used symbolically to represent Yeshua’s shedding his blood on the cross. The blood of a lamb was put on the door posts to protect men from YHVH’s judgment against sin (Exod 12:7, 13). Moses sprinkled the blood of oxen on the people symbolizing their coming into covenantal relationship with YHVH (Exod 24:5–8). Additionally, the blood of sacrificed animals was sprinkled throughout the tabernacle, on Aaron and his sons, and all around the altar to sanctify it. All these acts and uses of the blood were illustrative of the unrestricted cleansing power of the blood of Yeshua (Rev 1:5; 7:14; 12:11; 1 Pet 1:2, 19; Heb 9:12; 10:19–22; 12:24; 1 John 1:7; Matt 26:28), which is why YHVH expected his people to treat the blood with a reverence. Those who didn’t evidenced a heart of indifference for the set-apart or kadosh things of Elohim—an intolerable offence in the Creator’s eyes.
On the dark and satanic side, the blood of humans and animals is profaned through demonic rituals involving drinking it and even cannibalism. This is an abominable perversion of holy communion and was an aspect of ancient heathen religions (Ps 16:4; Ezek 39:17, 19 cp. Num 13:32), and is a practice in which the end time antichrist heathens of the Babylonian whore system will engage (Rev 17:6; 18:13, 24).
