Albert Barnes Commentary Ezekiel 41:22

"The altar was of wood, three cubits high, and the length thereof two cubits; and the corners thereof, and the length thereof, and the walls thereof, were of wood: and he said unto me, This is the table that is before Jehovah." — Ezekiel 41:22 (ASV)

The altar of wood — The altar for incense (marginal reference); also called the altar of gold (see 1 Kings 7:48).

Walls — The corner pieces of the altar, rising into projections called horns in Exodus, and corners here.

Table — “Table and altar” were convertible terms (Malachi 1:7).
