Gephen appears 55 times in the Hebrew Bible and refers primarily to the cultivated grapevine (Vitis vinifera), though rarely to wild vines. Grapes were among Israel's most important crops — the vine, along with fig and olive, constituted the triad of 'the good land.' Wine from the vine was central to worship (drink offerings), meals, medicine, and celebration. The vine was so central to Israelite identity that it appears on Hasmonean coins and synagogue architecture.
The theological symbolism of gephen is profound. Israel is repeatedly called God's vine, planted by his hand and tended by his care. Isaiah 5:1-7 is the 'Song of the Vineyard' — a parable of God's disappointment with Israel, his carefully cultivated vine that produced wild grapes instead of justice. Psalm 80 portrays Israel as a vine God transplanted from Egypt. Ezekiel and Hosea use the metaphor of the failing vine for Israel's apostasy. In John 15, Jesus declares 'I am the true vine' — identifying himself as the fulfillment of Israel's identity, the one through whom fruitful union with God is possible.
