Bede the Venerable — as excerpted in the Catena Aurea on Luke 20:9-18

“By the other servant is meant David, who was sent after the commandment of the law, that he by the music of his psalmody might stir up the husbandmen to the exercise of good works. But they on the contrary declared, What portion have we in David, neither have we inheritance in the son of Jesse. (1 Sam. 20:1.). Hence it follows, And they beat him also, and entreated him shamefully, and sent him away empty. (1 Kings 12:16.) But He does not stop here, for it follows, And again he sent a third: whereby we must understand the company of prophets who constantly visited the people with their testimony. But which of the Prophets did they not persecute; as it follows, And they wounded him also, and cast him out. Now these three successions of servants, our Lord elsewhere shews to comprehend under a figure all the teachers under the law, when He says, For all those things must be fulfilled which were written in the law of Moses, and the Prophets, and the Psalms, concerning me.”
