The True Vine (Greek: ἡ ἄμπελος ἡ ἀληθινή hē ampelos hē alēthinē) is an allegory or parable given by Jesus in the New Testament. Found in John 15:1–17, it describes Jesus' disciples as branches of himself, who is described as the "true vine", and God the Father the "husbandman".
There are numerous Old Testament passages which refer to the people of Israel as a vine (Hebrew: גָּ֫פֶן gephen): Psalm 80:8-16, Isaiah 5:1-7, Jeremiah 2:21, Ezekiel 15:1-8, 17:5–10, and 19:10–14, and Hosea 10:1.
The Old Testament passages which use this symbolism appear to regard Israel as faithless to God and/or the object of severe punishment. Ezek 15:1–8 in particular talks about the worthlessness of wood from a vine (in relation to disobedient Judah). A branch cut from a vine is worthless except to be burned as fuel. This appears to fit more with the statements about the disciples than with Jesus’ description of himself as the vine.
