Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 20:9-18

“After the prophets then had suffered all these things, the Son is delegated; for it follows, Then said the Lord of the vineyard, What shall I do? That the Lord of the vineyard speaks doubtingly, arises not from ignorance, for what is there that the Lord knows not? but He is said to hesitate, that the free will of man may be preserved.”
