This precept was given as early as in the days of Noah. So leading a doctrine was the atonement, that even then it was held forth in these distant allusions. See Genesis 9:4-5; Leviticus 3:17.

Leviticus 17:10-12
10 And whatsoever man there be of the house of Israel, or of the strangers that sojourn among you, that eateth any manner of blood; I will even set my face against that soul that eateth blood, and will cut him off from among his people.
11 For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul.
12 Therefore I said unto the children of Israel, No soul of you shall eat blood, neither shall any stranger that sojourneth among you eat blood.
