'Drink Offerings' in the Bible

Grain and drink offerings have been cut offfrom the house of the Lord;the priests, who are ministers of the Lord, mourn.

Dress in sackcloth and lament, you priests;wail, you ministers of the altar.Come and spend the night in sackcloth,you ministers of my God,because grain and drink offeringsare withheld from the house of your God.
