מדרש אויף ויקרא 1:11

1) "northward before the L–rd": The north must be empty (so that it is "before the L–rd.") These are the words of R. Eliezer b. Yaakov. The altar was aligned with half the opening of the heichal (the sanctuary), and opposite one of the doors, extending south. R. Yehudah says: The altar was in the mid-point of the azarah, thirty-two amoth — ten amoth opposite the entrance of the heichal, eleven amoth to the north, and eleven amoth to the south. So that the altar is found to be aligned with the sanctuary and its walls.

1) (Vayikra 1:3-4): "… before the L–rd. And he shall place (his hand on the head of the olah"): There is no semichah on a bamah (a temporary altar, it not being considered " before the L–rd"). (Vayikra 1:11): ("And he shall slaughter it on the side of the altar) northward (tzafonah), before the L–rd": There is no tzafon (requirement) on a bamah. Now which measure is greater? That of tzafon or that of semichah? The measure of tzafon is greater. For tzafon obtains both with individual and with communal offerings, whereas semichah obtains only with individual offerings. If I exclude them (bamoth) from tzafon, the greater measure, would I not exclude them from semichah, the lesser measure? (Why, then, is the exclusion verse for bamoth re semichah necessary) Perceived thus, tzafon is the greater measure, and semichah, the lesser. But perceived otherwise, semichah is the greater measure and tzafon the lesser. For semichah obtains with both higher and lower-order offerings, whereas tzafon obtains only with higher-order offerings. If I exclude them (bamoth) from tzafon, the lesser measure, I would not exclude them from semichah, the greater measure. So that because there obtains with tzafon what does not obtain with semichah, and with semichah, what does not obtain with tzafon; it is, therefore, written: "before the L–rd, vesamach" — there is no semichah on a bamah. "tzafonah before the L–rd" — there is no tzafon on a bamah. "before the L–rd vesamach": Even if he performed semichah outside (the azarah), he must return and perform it inside ("before the L–rd").

“He shall slaughter the young bull before the Lord, and Aaron’s sons, the priests, shall present the blood, and cast the blood all around on the altar that is at the entrance of the Tent of Meeting” (Leviticus 1:5).
“He shall slaughter the young bull…” Regarding the ram it says: “To the north…before the Lord” (Leviticus 1:11). [The Sages] said: When Abraham our patriarch bound Isaac his son, the Holy One blessed be He prepared two sheep, one for the morning and one for the evening.³²God decided to command Israel to bring the daily offering of a sheep in the morning and a sheep in the evening. Why to that extent? It is because when Israel would sacrifice a daily offering on the altar and read this verse: “To the north…before the Lord,”³³There was no obligation to read this verse upon the offering of the sacrifice. The point is that they fulfilled that verse. Alternatively, when Israel reads the verse today, when they cannot bring the offering (Etz Yosef). the Holy One blessed be He would remember the binding of Isaac.
I call the heavens and the earth to testify for me³⁴This statement is attributed to Elijah the prophet (Tanna d’Vei Eliyahu 7). that both gentile and Israelite, both man and woman, both slave and maidservant, when they read this verse: “To the north…before the Lord,” the Holy One blessed be He remembers the binding of Isaac, as it is stated: “To the north…before the Lord.”
Another matter, “to the north [tzafona]…before the Lord,” refers to the actions of Abraham, Isaac, and Jacob, which are preserved before Him. From where is it derived that tzafona is an expression of preservation? As it is stated: “New and old as well, I preserved [tzafanti] them for you, my beloved” (Song of Songs 7:14). Abraham, Isaac, and Jacob are “old,” Amram son of Kehat and all the upright who were in Egypt are “new,” as it is stated: “New and old as well.”
The company of Moses, the company of Joshua, the company of David and of Hezekiah – “old.” The company of Ezra, Hillel, Rabbi Yoḥanan ben Zakkai, Rabbi Meir and his colleagues – “new.” In their regard it says: “Old and new as well.”
