Matthew 21:37

37. Last of all… his son Let it be remembered that this parable is uttered on occasion of their demanding by what authority he did these things, (Matthew 21:23.) Jesus first confounds them by asking a question they could not answer, (24-27.) He then propounds a parable, (28-32,) portraying their spirit in asking the question. In the present parable he is obliging them to perceive the answer he could give to their demand for his authority. The same authority that sent God’s messengers of old to your fathers, has in these last days sent to you his Son. They will reverence my son These words represent God’s rightful expectation; that is, the expectation he has a right to have. If a human householder would have such an expectation, much more God has a reason and a right to expect reverence for his Son.
