Numbers 28:7-8

7Then the drink offering with it will be one litre of wine for each lamb. In God's Holy Tent, you must pour out a drink offering of the best wine to the Lord.

8You must offer the other lamb when it begins to get dark. Offer it with a grain offering and a drink offering like the offerings in the morning. You must give it as an offering by fire. The smell of the smoke from these sacrifices will make the Lord happy.
