'Vine' in the Bible

"I am the true vine, and my Father is the vinedresser.

Remain in me, and I in you. Just as the branch is not able to bear fruit from itself unless it remains in the vine, so neither [can] you, unless you remain in me.

"I am the vine; you [are] the branches. The one who remains in me and I in him--this one bears much fruit, for apart from me you are not able to do anything.
