Commentaire sur Le Lévitique 19:26

לא תאכלו על הדם YE SHALL NOT EAT ANYTHING על הדם — This text is interpreted in many different ways in Treatise Sanhedrin 63a: It is taken as a prohibition of eating the flesh of the sacrifices before their blood has been sprinkled; and as a prohibition addressed to him who eats of the flesh of a non-consecrated animal (חולין) before life has entirely left it; and many other interpretations are there given.

YE SHALL NOT EAT WITH THE BLOOD. “This passage has been explained in many different ways in Tractate Sanhedrin.”¹⁶⁹Sanhedrin 63 a. See “The Commandments,” Vol. II pp. 401-2, where all these various interpretations are listed. This is the language of Rashi. Now the conclusion of that discussion in the Talmud is that all those interpretations [of the verse before us] are Torah-ordained, since Scripture included all manner of “eating with the blood” in one negative commandment. And if so, that which Scripture states in the case of Saul, Behold, the people sin against the Eternal, in that they eat with the blood,¹⁷⁰I Samuel 14:33. means that they transgressed one of the prohibitions included in this negative commandment, since they were eating of an animal [slaughtered properly] before its life had entirely left it. It is with reference to this that Scripture states there, And the people flew upon the spoil,¹⁷¹Ibid., Verse 32. like a bird of prey that tears its victim and eats it, and they took sheep, and oxen, and calves, and slew them on the ground; and the people did eat them with the blood.¹⁷¹Ibid., Verse 32. Because of the abundance of spoil of cattle [that they had taken from the Philistines], as soon as [they were slaughtered properly and] their blood was spilled on the ground, they tore off their limbs and ate them before life had entirely left the animals.
In line with the plain meaning of Scripture, this seems to have been a kind of witchcraft or divination, since [the meaning of this passage] may be deduced from its context; [i.e., from the second half of this verse which states, neither shall ye practice divination nor soothsaying, we may deduce that the first half of the verse, Ye shall not eat with the blood also refers to some form of witchcraft, as will be explained]. Thus they used to spill the blood [of the cattle] and gather it in a hollow, which was then attended, according to their opinion, by the satyrs, and they¹⁷²I.e., the satyrs. Having assembled around the blood, the satyrs would then be present at the meal, at which time they would inform the people of future events. All this was part of this particular kind of witchcraft. would eat at their tables to tell them future events. Now when the Israelites were at that time camping with Saul, they were very much afraid of the Philistines, and Saul did nothing except for inquiring of the Urim and Thummim,¹⁷³Exodus 28:30. See Ramban there (Vol. II, pp. 480-484). as it is said, Let us draw near hither unto G-d,¹⁷⁴I Samuel 14:36. while the people were inquiring of the satyrs or of witchcraft to know their way and what to do, and they were eating with the blood in order to perform that craft [mentioned above]. It is for this reason that Scripture there states, Then they told Saul, saying: ‘Behold, the people sin against the Eternal, in that they eat with the blood.’ And he said: ‘Ye have dealt treacherously,’¹⁷⁵Ibid., Verse 33. meaning to say: “Behold, G-d has wrought for you this day this great salvation, and you inquire of no-gods! It is treachery!” I will yet explain the prohibition against soothsaying and enchanting.¹⁷⁶Deuteronomy 18:9.

לא תאכלו על הדם לא תנחשו ולא תעננו, all of these practices were commonplace also among the Israelites who were desperate to gain advance knowledge of what was in store for them individually. Such practices had to be eradicated if the people were to progress from an overall environment of spiritual morass, רוח טומאה, to spiritual bliss, רוח טהרה ונבואה, spiritual purity and prophetic spirit.
