Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 19:11-27

“For seeing that he gained ten, by multiplying his pound tenfold, it is plain that by having more to multiply, he would be an occasion of greater gain to his Lord. But from the slothful and idle, who stirs not himself to increase what he has received, shall be taken away even that which he possesses, that there may be no gap in the Lord’s account when it is given to others and multiplied. But this is not to be applied only to the words of God and teaching, but also to the moral virtues; for in respect of these also, God sends us His gracious gifts, endowing one man with fasting, another with prayer, another with mildness or humility; but all these so long as we watch strictly over ourselves we shall multiply, but if we grow cold we shall extinguish. He adds of His adversaries, But those mine enemies who would not that I should reign over them, bring them hither, and slay them before me.”
