John Gill Commentary Exodus 40:29

"And he set the altar of burnt-offering at the door of the tabernacle of the tent of meeting, and offered upon it the burnt-offering and the meal-offering; as Jehovah commanded Moses." — Exodus 40:29 (ASV)

And he put the altar of burnt offering by the door of the
tabernacle of the tent of the congregation
Of which see (Exodus 40:6)

and offered upon it the burnt offering and the meat offering ;
either the burnt offering the meat offering of the daily sacrifice, as Jarchi interprets it, see (Exodus 28:38–42) or it may be rather the burnt offering and meat offering of the consecration of Aaron and his sons, (Exodus 29:1Exodus 29:2Exodus 29:18Exodus 29:23)

as the Lord commanded Moses ;
in the places referred to.
