Why the Altar Rested in Benjamin's Portion

Two applications of blood that are four: how does one do it? Rav and Shmuel disagree. One says he places the blood and then places it again; the other says a single application shaped like the Greek letter gamma. This follows a dispute among the Tannaim: "and they shall sprinkle," one might think a single sprinkling, and so on, until "so too here an interrupted set of four applications." If, like there, four applications upon four corners, so too here four applications upon four corners? You said: the burnt offering requires a base, and the southeastern corner had no base. What is the reason? Rabbi Elazar said: Because it was not in the portion of the predatory one [Benjamin, called "a wolf that tears"]. Rabbi Yishmael son of Rabbi Yitzchak said: The altar consumed one cubit within the portion of Judah. Rabbi Levi bar Chama said in the name of Rabbi Chama bar Chanina: A strip extended out from the portion of Judah and entered the portion of Benjamin, and upon it the altar was built, and Benjamin the righteous would grieve over it every day, as it is said, "He covers him all the day" (Deuteronomy 33:12). Therefore Benjamin the righteous merited to become the host of the Divine Power, as it is said, "and he dwells between his shoulders" (Deuteronomy 33:12). They raised an objection: How was the bird burnt offering performed? He would go up the ramp and turn to the surrounding ledge, come to the southeastern corner, pinch off its head from the back of the neck, sever it, and drain its blood upon the wall of the altar. And if he performed it below his feet, even a single cubit, it is valid. Now if you say it had no base, he would merely be placing it into thin air? Rav Nachman bar Yitzchak said: Thus they arranged it, the ground belonging to Judah and the air space to Benjamin. What is meant by "it had no base"? Rav said, in its structure; and Levi said, with respect to the blood. Rav renders the verse: in his inheritance the altar shall be built; and Levi renders it: in his inheritance the Sanctuary shall be built, a place sanctified for the blood.
