'Libations' in the Bible

Then he offered his burnt offerings and his grain offerings, he poured his libations and dashed the blood of his fellowship offerings against the altar.

And king Ahaz commandeth him -- Urijah the priest -- saying, 'On the great altar perfume the burnt-offering of the morning, and the present of the evening, and the burnt-offering of the king, and his present, and the burnt-offering of all the people of the land, and their present, and their libations; and all the blood of the burnt-offering, and all the blood of the sacrifice, on it thou dost sprinkle, and the altar of brass is to me to inquire by.'
