Metaphors for vine and vineyards are common in the Bible for a reason. Most people would have been familiar with the process of growing and tending grape vines. The disciples, being Jewish, would have recognized references to vines from the Old Testament. Jeremiah 2:21, for instance, compares the nation of Israel to a vine that was planted but then turned wild. Passages such as Ezekiel 15, Isaiah 5:1–7, and Hosea 10:1 continue this analogy.
