Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 18:18-23

“The law first forbids those things to which we are most prone, as adultery for instance, the incitement to which is within us, and of our nature; and murder, because rage is a great and savage monster. But theft and bearing false witness are sins which men seldom fall into. And besides, the former also are the more grievous sins, therefore He places theft and bearing false witness in the second place, as both less common, and of less weight than the other.”
