Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 12:1-3

“The Pharisees sought indeed to catch Jesus in His talk, that they might lead away the people from Him. But this design of theirs is reversed. For the people came all the more unto Him gathered together by thousands, and so desirous to attach themselves to Christ, that they pressed one upon another. So mighty a thing is truth, so feeble every where deceit. Whence it is said, And when there were gathered together a great multitude, insomuch that they trode upon one another, he began to sag unto his disciples, Beware ye of the leaven of the Pharisees, which is hypocrisy.”
