'Altar' in the Bible

Put on sackcloth and mourn, you priests! Wail, you ministers of the altar. Come, lie all night in sackcloth, you ministers of my God, for the meal offering and the drink offering are withheld from your God's house.

Let the priests, the ministers of Yahweh, weep between the porch and the altar, and let them say, "Spare your people, Yahweh, and don't give your heritage to reproach, that the nations should rule over them. Why should they say among the peoples, 'Where is their God?'"
