Leviticus 10:11

11. That ye may teach The priest was the earliest religious teacher of the Levitical law, “for the priest’s lips should keep knowledge, and they should seek the law at his mouth.” Malachi 2:7. The two sides of the priestly vocation, teaching and offering, are embraced in Deuteronomy 33:10. The Pentateuch knows nothing of a scholastic inculcation of the divine laws; it knows no formal religious instruction at all except the reading of the law before the assembled people, at the feast of tabernacles, in the Sabbatic year. Deuteronomy 31:10-13. All religious teachers should be τελειοι , perfect, having their senses internal and external exercised to discern or discriminate both good and evil. Hebrews 5:14. Wine draws a film over the spiritual eye and confounds moral distinctions. If the priests have aught to do with wine in a lawful way, it is only that it may, in the holy place,” be poured unto the Lord for a drink offering.”

Numbers 28:7. Wine symbolizes joy. The joy of all believers is not the joy of earth but of heaven of the sanctuary. “The joy of the Lord is your strength.”
