'Servants of the Lord' in the Bible

Both grain offering and wine offering have been removed from the LORD's Temple; the priests and ministering servants of the LORD are mourning."

Let the priests, the servants of the Lord, be weeping between the covered way and the altar, and let them say, Have mercy on your people, O Lord, do not give up your heritage to shame, so that the nations become their rulers: why let them say among the peoples, Where is their God?
