This parable is remarkable for the codicil taken from the Old Testament and attached to it by the Lord on the spot and at the moment. The picture of the tenant vine-dressers usurping possession--driving off the owner's servants and slaying his son, although transparent in its meaning and pungent in its reproof, does not contain all that the Lord then desired to address to the Pharisees. It pleased him to employ that similitude as far as it reached; but when its line had all run out, he seized another line that lay ready in the Scriptures to his hand, and attached it to the first, that by the union of the two he might make the reproof complete. The first type taken from human affairs is not broad enough to represent the kingdom of God at a crisis of its conflict. The son whom the proprietor sends on an embassy to the vine-dressers, points to Christ sent by the Father to his own Israel. The terrestrial fact serves to show that the son was put to death by the rebels in possession, but there its power is exhausted; it has no means of exhibiting the other side of the scene,--that this son rose from the dead, and now reigns over all. The parable, when it came to its natural conclusion, left the lesson which it had begun to teach abruptly broken off in the midst,--left a glory of the Lord unrevealed, and a terror to wicked men unspoken. That he might proclaim the whole truth, and leave his unrepenting hearers without excuse, the Lord proceeded then and there to demand of them, "Did ye never read in the Scriptures, The stone which the builders rejected, the same is become the head of the corner?"
