When Jesus said “I am the true vine, and my Father is the vinedresser” (John 15:1), His illustration was understood by all of His hearers. The same is true of those who heard and read Isaiah 5. Read it for yourself and then look at the beautiful photo of a vineyard with a watchtower in it near Bethlehem.
Let me sing for my beloved my love song concerning his vineyard: My beloved had a vineyard on a very fertile hill.
2 He dug it and cleared it of stones, and planted it with choice vines; he built a watchtower in the midst of it, and hewed out a wine vat in it; and he looked for it to yield grapes, but it yielded wild grapes.
3 And now, O inhabitants of Jerusalem and men of Judah, judge between me and my vineyard.
4 What more was there to do for my vineyard, that I have not done in it? When I looked for it to yield grapes, why did it yield wild grapes?
5 And now I will tell you what I will do to my vineyard. I will remove its hedge, and it shall be devoured; I will break down its wall, and it shall be trampled down.
6 I will make it a waste; it shall not be pruned or hoed, and briers and thorns shall grow up; I will also command the clouds that they rain no rain upon it.
7 For the vineyard of the LORD of hosts is the house of Israel, and the men of Judah are his pleasant planting; and he looked for justice, but behold, bloodshed; for righteousness, but behold, an outcry! (Isaiah 5:1-7 ESV)
