Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 12:13-15

“This our Lord says to rebuke the motives of the covetous, who seem to heap up riches as if they were going to live for a long time. But will wealth ever make thee long lived? Why then dost thou manifestly undergo evils for the sake of an uncertain rest? For it is doubtful whether thou oughtest to attain to an old age, for the sake of which thou art collecting treasures.”
