Luke 20:11

And it came to pass that He ordained many others, whom the Jews sent back to him disgraced and empty, for they could reap nothing from them; as it follows, And again he sent another servant.

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.)

And he added the sending of another servant. But they also beat him and treated him shamefully, and sent him away empty-handed. The other servant signifies David the prophet and king. Who was sent after Moses, to urge the tenants of the vineyard, through the modulation of psalmody and the sweetness of the lyre, to the practice of good work after the legal decrees. For David himself also sought to lift the heart of the people to higher things, establishing that the praises of the Lord be sung continuously with sweet melody among the rites of carnal sacrifices. But even him they treated shamefully and sent away empty-handed. For they said: "What portion have we in David? Neither have we inheritance in the son of Jesse" (1 Kings 12). They changed David's kingdom with an ignoble lineage and the religion with impiety. Yet he intercedes that this vineyard, which, transplanted from Egypt, covered the mountains of Palestine with its shadow, might not be utterly destroyed. "O Lord God of hosts, turn now, look down from heaven, and see, and visit this vineyard, and protect the branch that your right hand has planted" (Ps. 80). Where he also explains who the man is who planted this vineyard, namely the Lord God of hosts.
