Numbers 15:5

5. Wine for a drink offering This was not to be drunken by the priest, but a part of it was to be poured out. See 2 Timothy 4:6, note on σπενδομαι , “I am already poured,” as a drink offering. According to Deuteronomy 14:23-27, a part of the wine was to be drank by the offerer and his family after he had presented his peace offering and partaken of the meat, (bread,) when he appeared before the Lord with his household, accepted through the atonement then made, and therefore entitled to share in the blessings so procured. Hence the inference that bread and wine were, even under Mosaism, the joyous emblems of conscious salvation through the atonement. Wine is a symbol of joy.
