The altar of wood. — This is what was known in the tabernacle (Exodus 30:1-3) as the altar of incense, and in the Temple as the altar of gold (1 Kings 7:48), although here its dimensions are enlarged.
The corners thereof. — This doubtless includes the “horns,” or projecting pieces at the corners, which were always an important part of the symbolism of the altar. The expression “length” in its repetition is generally thought to mean (by a slight change in the text) “the stand” or “base.” Table and altar are used synonymously, as in Malachi 1:7.
