Yayin (יַיִן) is the primary Hebrew word for wine, appearing over 140 times in the Old Testament. It refers to fermented grape juice and is the most general term for wine in Hebrew, distinct from tirosh (new/fresh wine). Wine in the biblical world was both a daily staple and a symbol of abundance, covenant celebration, and at times, moral danger.
Yayin carries a profound dual character in the Old Testament. On one side, wine is a gift of God: it 'gladdens the heart of man' (Psalm 104:15) and flows abundantly in covenant blessing (Joel 3:18). The absence of wine signifies divine judgment (Isaiah 24:11). Yet wine also represents moral peril — it deceives (Proverbs 20:1), leads to folly (Isaiah 28:7), and is linked to idolatrous feasting (Daniel 5:2). Wisdom literature warns against excess. The same gift can bless or destroy depending on the heart that receives it. The New Testament transforms this imagery in the Lord's Supper, where wine becomes the cup of the new covenant.
