Another matter: “Your hair is like a flock of goats” (Song of Songs 4:1) – the mountain from whose midst you took away, I rendered a memorial for the nations of the world. Which is this? This is the Sanhedrin. What is it that you took from its midst?
“Your teeth are like a flock of ordered ewes” (Song of Songs 4:2) – defined matters, these exonerate and these convict.59The Sanhedrin is compared to “ordered ewes” because there were a specific number of judges and specific guidelines for arriving at a verdict when the judges were split in their decision. “That have come up from bathing” (Song of Songs 4:2) – who exonerate Israel. “That are all paired” (Song of Songs 4:2) – as we learned: If they found in his favor they exonerate him.
But if not they delay to the following day, and spend [the time in] pairs (Sanhedrin 40a).60In cases of capital punishment, the judges would spend the interval in the case in pairs, deliberating about whether there was any way to exonerate the accused. “And there is none missing among them” (Song of Songs 4:2) – Rabbi Levi said: They infer one matter from another matter. Rabbi Abba said: That the halakha is not unclear to them.
“Your lips are like a scarlet thread” (Song of Songs 4:3) – Rabbi Yudan said: The decree of the court is like the decree of the king; with their mouths they command stoning, burning, beheading, and strangulation. Rabbi Ḥunya said: Blood,61Rabbi Ḥunya interprets the phrase “your lips are like a scarlet thread” as praising Israel for their observance of the laws of sacrificial offerings. as we learned: A red line encircled in the middle [of the altar] to separate between the blood of the upper part [of the altar] and the blood of the lower part (Midot 3:1).
Rabbi Azarya [said] in the name of Rabbi Yuda: Just as the red line separates between the upper and the lower blood, so the Sanhedrin distinguishes between impurity and purity, between the prohibited and the permitted, between exemption and liability.
