Any person who eats any blood, even that person shall be CUT OFF FROM HIS PEOPLE

[TonyChanYT]

Leviticus 7:

27 Any person who eats any blood, even that person shall be cut off from his people.

What did "cut off from his people" mean?

Leviticus 17 offered some insight:

10 any man from the house of Israel, or from the aliens who sojourn among them, who eats any blood, I will set My face against that person who eats blood and will cut him off from among his people.

Would this simply mean they were cast out of the camp and never welcomed back?

Wiki:

The Hebrew term kareth ("cutting off" Hebrew: כָּרֵת‎, [kaˈret]) is a form of punishment for sin ... In the Talmud, kareth means not necessarily physical "cutting off" of life, but extinction of the soul and denial of a share in the world to come. ...
In the Hebrew Bible, kareth is a form of punishment which may mean premature death, or else exclusion from the people.[3][4] According to Richard C. Steiner, the phrase "to be cut off from one's people" is an antonym for "to be gathered to one's people" (e.g. Genesis 25:8), and thus kareth in the Bible means to be deprived of the afterlife.[5]
Examples of sins making a person liable to kareth include eating chametz on Passover,[6] sexual violations,[7] ritual impurities, and a man's refusal to be circumcised.[8] The Book of Numbers states that anyone who sins deliberately or high-handedly receives kareth.

Rabbinic interpretation:

Kareth is the punishment for certain crimes and offences defined under Jewish law (e.g. eating the life blood of a living animal, eating suet, refusing to be circumcised, etc.), a punishment that can only be given at the hand of heaven unto persons of the Jewish faith who are bound to keep the Jewish law, rather than made punishable by any earthly court. In some cases of sexual misconduct and in breaking the laws of the Sabbath, such as where there are witnesses of the act, the court is able to inflict punishment. By definition, kareth does not apply to non-Jews. Kareth can either mean dying young (before the age of 50 or 60[10]), dying without children, or the soul being spiritually "cut off" from your people after death.[11] According to Nachmanides, both definitions are accurate

What did "cut off from his people" mean?

He would no longer be a citizen of God's kingdom of Israel.

Now check Acts 3 and the new Moses.

 

[Mr GLee]

Now check Acts 3 and the new Moses.

The doctrine of blood used in parables. . .that compare the temporal things seen to the eternal things of God not seen must first be defined or its seems one would be chasing his own tail .

it would seem the Holy Spirit of life works in the flesh but is not literal blood without the Holy Spirit of life .

Living sacrifice. The literal blood must be poured so it could return to the field of clay to show Holy Spirit life was given. Literal blood is used in the same way as water both metaphors used in parables .

Both represent Christ pouring out His Holy Spirit life on dying mankind in jeapordy of his own Holy Spirit life. The demotion on the cross both water and blood returned to dust to represent the work of the Holy Spirt.
