Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 22:47-53

“The disciples are inflamed with zeal, and unsheath their swords. But whence have they swords? Because they had slain the lamb, and had departed from the feast. Now the other disciples ask whether they should strike; but Peter, always fervent in defence of his Master, waits not for permission, but straightway strikes the servant of the High Priest; as it follows, And one of them smote, &c.”
