'Altar' in the Bible

Gird yourselves, and lament, ye priests; howl, ministers of the altar; come, lie all night in sackcloth, ye ministers of my God: for the oblation and the drink-offering are withholden from the house of your God.

Let the priests, the ministers of Jehovah, weep between the porch and the altar, and let them say, Spare, O Jehovah, thy people, and give not thine inheritance to reproach, that they should be a byword of the nations. Wherefore should they say among the peoples, Where is their God?
