'Altar' in the Bible

Gird, and lament, ye priests, Howl, ye ministrants of the altar, Come in, lodge in sackcloth, ministrants of my God, For withheld from the house of your God hath been present and libation.

Between the porch and the altar weep let the priests, ministrants of Jehovah, And let them say: 'Have pity, O Jehovah, on Thy people, And give not Thy inheritance to reproach, To the ruling over them of nations, Why do they say among peoples, Where is their God?'
