Commentaries:
The owner's waiting signifies the delay of vengeance, to give Israel an opportunity to repent. Knowing that the vineyard's owner had every reason to be disappointed with the barren tree, the keeper intercedes for the tree's life, asking for another year. He does not plead for its indefinite existence, but for an opportunity to stimulate it into fruitfulness by imposing more dramatic measures. If it bears fruit after further treatment, then the keeper knows that the owner will be pleased to allow the tree to remain in the vineyard. The keeper asks only for the owner to postpone judgment.
In the intercessory plea of the keeper, we have an illustration of Jesus' reluctance to let Israel go. During His life, Jesus prayed for fruitless Israel to repent (Matthew 23:27; Mark 1:15; Luke 23:34). In answer, God sent the apostles to provide Israel another opportunity to repent, as they fertilized Israel with God's truth (Matthew 10:6; Luke 24:46-47; II Timothy 2:25-26).
