You shall make an altar of earth for Me, and sacrifice on it your burnt offerings and your peace offerings, your sheep and your oxen. In every place where I cause My Name to be recorded and remembered [through revelation of My divine nature] I will come to you and bless you.

If you make an altar of stone for Me, you shall not build it of cut stones, for if you use a chisel on it, you will profane it.

There you shall build an altar to the Lord your God, an altar of stones; you shall not use an iron tool on them.

Then the Angel of the Lord put out the end of the staff that was in His hand and touched the meat and the unleavened bread; and fire flared up from the rock and consumed the meat and the unleavened bread. Then the Angel of the Lord vanished from his sight.

“And you shall make the altar [for burnt offerings] of acacia wood, five cubits long and five cubits wide; the altar shall be square, and its height shall be three cubits.

You shall make pots to remove its ashes, and shovels, basins [to catch the blood of the sacrificed animal], meat-forks, and firepans [to store live coals]. You shall make all its utensils of bronze. read more.
Also make a grate for it, a network of bronze; and on the grid you are to make four bronze rings at its four corners. And you shall put it under the ledge of the altar, so that the grid will extend halfway up the altar. You shall make [carrying] poles for the altar, poles of acacia wood, overlaid with bronze.
