 They are regarded as a sacrifice, not to make an atonement for sin, but as a poured-out drink offering. The first reference to a drink offering is found in Genesis 35, 14, which says, Jacob set up a pillar in the place where he talked with him, or talked with God, even a pillar of stone, and he poured a drink offering thereon. The drink offering was made of wine, not to be drunk, but to be poured out.
