Jerome

And they apprehended him, cast him out of the vineyard, and killed him. And the Apostle speaks, that Jesus was crucified outside the gate (Heb. 13). We can also understand it differently; that he was cast out of the vineyard, and there he was killed: so that when the gentiles received him, the vineyard would be given to others.

Hilary of Poitiers

Christ was cast out of Jerusalem, as out of the vineyard, to His sentence of punishment.

Catena Aurea by Aquinas ↗

Thomas Aquinas

Then the execution is presented: "and taking him, they cast him forth out of the vineyard, and killed him," because they crucified him outside the gate of the city, and so they killed him as though a stranger to the vineyard. Isa 53:7: "He was led as a sheep to the slaughter" etc. That they cast him out of the vineyard is found in John, that whoever confessed the name of Christ was cast out of the synagogue.
