9 In those days Jesus came from Nazareth of Galilee and was baptized by John in the Jordan. 10 And when he came up out of the water, immediately he saw the heavens being torn open and the Spirit descending on him like a dove. 11 And a voice came from heaven, “You are my beloved Son; with you I am well pleased.”
— John 1:9-11 (ESV)
My loved one had a vineyard on a fertile hillside. He dug it up and cleared it of stones and planted it with the choicest vines. He built a watchtower in it and cut a winepress as well. Then he looked for a crop of good grapes, but it yielded only bad fruit. — Isaiah 5:1–2 (ESV)
The normal method of payment for the tenancy was for an agreed proportion of the crop to be surrendered to the owner. In the case of a new vineyard it would be at least four years before a crop would be harvested, so that there is a long interval between the beginning of the tenancy and the καιρός for the sending of the collector; the tenants have had time to feel securely entrenched. The fact that those sent to collect the rent are δοῦλοι does not mean that they can easily be ignored. The slave of a rich landowner was himself a person of consequence. In not only refusing the rent but also assaulting and insulting the collectors the tenants are in the plainest terms repudiating the owner’s claim to the vineyard and challenging him to enforce payment if he can.
For it stands in Scripture: “Behold, I am laying in Zion a stone, a cornerstone chosen and precious, and whoever believes in him will not be put to shame.” — 1 Peter 2:6 (ESV)
