'Drink Offering' in the Bible

When I had brought them into the land which I swore to give to them, then they saw every high hill and every leafy tree, and they offered there their sacrifices and there they presented the provocation of their offering. There also they made their soothing aroma and there they poured out their drink offerings.

It shall be the prince’s part to provide the burnt offerings, the grain offerings and the drink offerings, at the feasts, on the new moons and on the sabbaths, at all the appointed feasts of the house of Israel; he shall provide the sin offering, the grain offering, the burnt offering and the peace offerings, to make atonement for the house of Israel.”
