Exodus 40:29

(29) He put the altar of burnt offering by the door of the tabernacle.—On the altar of burnt offering, see Exodus 27:1-8; Exodus 38:1-7. Some preposition has fallen out before the word “door.” Our translators suppose an omission of ’al, “at,” but it is more probable that liphney, which occurs in Exodus 40:6, is the word omitted. The altar was not “at the door,” but “before” or “in front of the door.”

And offered upon it the burnt offering and the meat offering.—Offered upon it, i.e., the first evening sacrifice—a lamb for a burnt offering, together with the prescribed meat offering. (See Exodus 29:40.)
