John Gill Commentary Exodus 35:15

"and the altar of incense, and its staves, and the anointing oil, and the sweet incense, and the screen for the door, at the door of the tabernacle;" — Exodus 35:15 (ASV)

And the incense altar, and his staves
Which were overlaid with gold; hence this altar was called the golden altar, of which see (Exodus 30:1–5)

and the anointing oil and sweet incense ;
each of which were made of various spices, see (Exodus 30:23–31)

and the hanging for the door at the entering in of the tabernacle ;
at the east end of it, there being there, as Jarchi observes, neither boards nor curtains; see (Exodus 27:16) .
