Rebbi Yose ben Rebbi Abun said, not for this reason but because we have stated: “All who enter the Temple Mount enter to the right, and turn, and leave to the left.¹⁵⁰Mishnah Middot2:2. One enters the priest’s courtyard from the East. If then one turns to the right one is on the North side of the altar. The incoming watch divide the bread at their place of entry. Correspondingly, the outgoing ones divide in the South; afterwards they may leave turning to the left, through the gate in the East.”
