'Altar' in the Bible

When the lamb opened the fifth seal, I saw under the altar the souls of those who had been slaughtered because of the word of God and the testimony they had given.

Another angel came with a gold censer and stood at the altar. He was given a large quantity of incense to offer on the gold altar before the throne, along with the prayers of all the saints.

The angel took the censer, filled it with fire from the altar, and threw it on the earth. Then there were peals of thunder, noises, flashes of lightning, and an earthquake.

When the sixth angel blew his trumpet, I heard a voice from the four horns of the gold altar in front of God.

Then I was given a stick like a measuring rod. I was told, "Stand up and measure the Temple of God and the altar, and count those who worship there.

From the altar came another angel who had authority over fire. He called out in a loud voice to the angel who had the sharp sickle, "Swing your sharp sickle, and gather the bunches of grapes from the vine of the earth, because those grapes are ripe."

Then I heard the altar reply, "Yes, Lord God Almighty, your judgments are true and just."
