And the 147th prohibition is that we are forbidden from consuming kodshim kalim before their blood is sprinkled.
The source of this prohibition is G‑d's statement,1 "In your settlements you may not eat [the tithes of your grain, wine, and oil, the firstborn of your cattle and your sheep, any animal you have vowed (to bring as an offering)] nor any animal you have promised [to bring as an offering]." [The beginning of the verse also applies to the last phrase, and therefore] it is as if the verse says, 'In your settlements you may not eat any animal you have promised [to bring as an offering].'
The Oral Tradition2 explains that this verse [which is otherwise redundant,] refers only to one who eats from the thanksgiving-offering or peace-offering before their blood is sprinkled — to teach you that he transgresses a prohibition. He, too, is punished by lashes.
