The principal altars among the Jews were those of incense, of burnt-offering, and the altar or table for the shew bread. The altar of incense was a small table of shittim wood covered with plates of gold. It was a cubit long, a cubit broad, and two cubits high. At the four corners were four horns. The priest, whose turn it was to officiate, burnt incense on this altar, at the time of the morning sacrifice between the sprinkling of the blood and the laying of the pieces of the victim on the altar of burnt-offering. He did the same also in the evening, between the laying of the pieces on the altar and the drink-offering. At the same time the people prayed in silence, and their prayers were offered up by the priests. The altar of burnt-offering was of shittim wood also, and carried upon the shoulders of the priests, by staves of the same wood overlaid with brass. In Moses’s days it was five cubits square, and three high: but it was greatly enlarged in the days of Solomon, being twenty cubits square, and ten in height. It was covered with brass, and had a horn at each corner to which the sacrifice was tied. This altar was placed in the open air, that the smoke might not sully the inside of the tabernacle or temple. On this altar the holy fire was renewed from time to time, and kept constantly burning. Hereon, likewise, the sacrifices of lambs and bullocks were burnt, especially a lamb every morning at the third hour, or nine of the clock, and a lamb every afternoon at three, Exod. xx, 24, 25; xxvii, 1, 2, 4; xxxviii, 1. The altar of burnt-offering had the privilege of being a sanctuary or place of refuge. The wilful murderer, indeed, sought protection there in vain; for by the express command of God he might be dragged to justice, even from the altar. The altar or table of shew bread was of shittim wood also, covered with plates of gold, and had a border round it adorned with sculpture. It was two cubits long, one wide, and one and a half in height. This table stood in the _sanctum sanctorum_, [holy of holies,] and upon it were placed the loaves of shew bread. After the return of the Jews from their captivity, and the building of the second temple, the form and size of the altars were somewhat changed.
