(Compare Exodus 38:1-7.) The great altar which stood in the court immediately in front of the tabernacle was commonly called the altar of burnt-offering, because on it were burnt the whole burnt-offerings, and all those parts of the other animal sacrifices which were offered to the Lord. It was also called the brazen altar, because it was covered with bronze, in distinction from the golden altar or altar of incense Exodus 39:38-39; Exodus 40:5-6.
His horns shall be of the same - These horns were projections pointing upward in the form either of a small obelisk, or of the horn of an ox. They were to be actually parts of the altar, not merely superadded to it. On them the blood of the sin-offering was smeared Exodus 29:12; Leviticus 4:7; Leviticus 8:15; Leviticus 9:9; Leviticus 16:18. To take hold of them appears to have been regarded as an emphatic mode of laying claim to the supposed right of sanctuary (Exodus 21:14 note; 1 Kings 1:50).
Pans - Rather pots as in Exodus 38:3; 1 Kings 7:45. On the use to which these pots were put in disposing of the ashes of the altar, see Leviticus 1:16.
Basons - Vessels used for receiving the blood of the victims and casting it upon the altar (see Exodus 24:6; Leviticus 1:5; etc.).
Fleshhooks - These were for adjusting the pieces of the victims upon the altar (compare 1 Samuel 2:13).
Firepans - The same word is rendered snuffdishes, Exodus 25:38; Exodus 37:23 : censers, Leviticus 10:1; Leviticus 16:12; Numbers 4:14; Numbers 16:6, etc. These utensils appear to have been shallow metal vessels which were employed merely to carry burning embers from the brazen altar to the altar of incense.
The compass of the altar - A shelf or projecting ledge, of convenient width, carried round the altar half way between the top and the base. It was supported all round its outer edge by a vertical net-like grating of bronze that rested on the ground.
Hollow with boards - Slabs, or planks, rather than boards. The word is that which is used for the stone tables of the law Exodus 24:12; Exodus 31:18, not that applied to the boards of the tabernacle Exodus 26:15.
The brazen altar was a hollow casing, formed of stout acacia planks covered with plates of bronze, seven feet six in length and width and four feet six in height. Jewish as well as Christian authorities have supposed that, when it was fixed for use, it was filled up with earth or rough stones. If we connect this suggestion with the old rule regarding the altar of earth and the altar of stone given in Exodus 20:24-25, the woodwork might in fact be regarded merely as the case of the altar on which the victims were actually burned. The shelf round the sides Exodus 27:5 was required as a stage for the priests to enable them to carry on their work conveniently on the top of the altar. Hence, it is said of Aaron that he came down from the altar Leviticus 9:22. According to rabbinical tradition, there was a slope of earth at the south side banked up for the priest to ascend to the stage (compare Exodus 20:26).
