Leviticus 1:11 - Matthew Poole's English Annotations on the Holy Bible

This and other kinds of sacrifices were killed on the side of the altar northward, Leviticus 6:25, Leviticus 7:2, because here seems to have been the largest and most convenient place for that work, the altar being probably near the middle of the east end of the building, and the entrance being on the south side; so the north side was the only vacant place. Besides, this might design the place of Christ's death, both more generally, to wit, in Jerusalem, which was in the sides of the north, Psalms 48:2; and more specially, to wit, on Mount Calvary, which was on the north and west side of Jerusalem.
