'Drink Offering' in the Bible

I brought them to the land which I swore to give them, but whenever they saw any high hill or leafy tree, they offered their sacrifices there and presented the offerings that provoke me to anger. They offered their soothing aroma there and poured out their drink offerings.

It will be the duty of the prince to provide the burnt offerings, the grain offering, and the drink offering at festivals, on the new moons and Sabbaths, at all the appointed feasts of the house of Israel; he will provide the sin offering, the grain offering, the burnt offering, and the peace offerings to make atonement for the house of Israel.
