2 and he digged it, and gathered out the stones thereof, and planted it with the choicest vine, and built a tower in the midst of it, and also hewed out a winepress therein: and he looked that it should bring forth grapes, and it brought forth wild grapes.
3 And now, O inhabitants of Jerusalem and men of Judah, judge, I pray you, betwixt me and my vineyard.
4 What could have been done more to my vineyard, that I have not done in it? wherefore, when I looked that it should bring forth grapes, brought it forth wild grapes?
7 For the vineyard of Jehovah of hosts is the house of Israel, and the men of Judah his pleasant plant: and he looked for justice, but, behold, oppression; for righteousness, but, behold, a cry.
The basic shape of a tower was known 9,000 years ago in Jericho. There were ruins of terraces and towers in the hills if Israel from before the times of Jesus and similar features exist to this day.
