'Drink Offering' in the Bible

And he burnt his burnt offering, and sprinkled the blood of his peace offering, and poured his drink offering and sprinkled the blood of his peace offerings upon the said altar.

And the king commanded Uriah the Priest, saying, "Upon the great altar set on fire, in the morning, burnt offerings; and in the evening, meat offerings and the king's burnt sacrifice and his meat offering, and the burnt offerings of all the people of the land and their meat offerings and their drink offerings, and pour thereon all the blood of all manner of offerings. But the brazen altar shall be for me, to enquire with."
