Northward before the Lord - That is, on the north side of the altar. See also Leviticus 4:24, Leviticus 4:29, Leviticus 4:33; Leviticus 7:2. This was probably an arrangement of some practical convenience. On the west side of the altar stood the laver; on the east side was the place of ashes (see Leviticus 1:16 note); and the south side, where appears to have been the slope by which the priests went up to the altar, must have been left clear for a path.
