'Altar' in the Bible

Then He said to me, “Son of man, now raise your eyes toward the north.” So I looked toward the north, and behold, to the north of the altar gate was this idol (image) of jealousy at the entrance.

So He brought me to the inner court of the Lord’s house. And behold, at the entrance to the temple of the Lord, between the porch (vestibule, portico) and the [bronze] altar, were about twenty-five men with their backs to the temple of the Lord and their faces toward the east; and they were bowing down toward the east and worshiping the sun.

Behold, six men [angelic beings] came from the direction of the Upper Gate, which faces north, each with his battle-axe in his hand; and among them was a certain man clothed in linen, with a scribe’s writing case at his side. They entered and stood beside the bronze altar.

but the chamber which faces toward the north is for the priests who have the responsibility and take care of the altar. These are the sons of Zadok, who [alone] from the sons of Levi come near to the Lord to minister to Him.”

He measured the courtyard, a hundred cubits long and a hundred cubits wide, a perfect square; and the altar was in front of the temple.

The altar was of wood, three cubits high and two cubits long; and its corners, its base, and its sides were wood. And he said to me, “This is the table that is before the Lord.”

“And these are the measurements of the altar [of burnt offering] in cubits (the cubit being a [long] cubit [the length of a forearm] and a hand width): the base shall be a cubit [long] and a cubit wide, with its border on its edge all around it of a span [in width]. And this shall be the height of the base of the altar.

The altar hearth shall be four cubits high, and from the altar hearth shall extend upwards four horns [one from each corner, each one cubit high].

Now the altar hearth shall be twelve cubits long by twelve wide, square in its four sides.

And He [the Lord] said to me, “Son of man, thus says the Lord God, ‘These are the statutes and regulations for [the use of] the altar on the day that it is built, to offer burnt offerings on it and to sprinkle blood on it.

And you shall take some of its blood and put it on the four horns [of the altar of burnt offering] and on the four corners of the ledge and on the border all around; thus you shall cleanse it (from sin) and make atonement for it.

‘On the second day you shall offer a male goat without blemish for a sin offering, and they shall cleanse the altar as they cleansed it with the bull.

For seven days they shall make atonement for the altar and purify it; so the priests shall consecrate it [to receive offerings].

When they have completed these days, on the eighth day and from then onward, the priests shall offer your burnt offerings on the altar, and your peace offerings; and I will accept you,’ says the Lord God.”

The priest shall take some of the blood of the sin offering and put it on the door posts of the temple, on the four corners of the ledge of the altar, and on the posts of the gate of the inner courtyard.

Then he [my guide] brought me back to the door of the house [the temple of the Lord]; and behold, water was flowing from under the threshold of the house (temple) toward the east, for the front of the temple was facing east. And the water was flowing down from under, from the right side of the house, from south of the altar.
