Matthew 12:23

And all the people were amazed, and said, Is not this the son of David?--The form of the interrogative requires this to be rendered, "Is this the Son of David?" And as questions put in this form (in Greek) suppose doubt, and expect rather a negative answer, the meaning is, "Can it possibly be?"--the people thus indicating their secret impression that this must be He; yet saving themselves from the wrath of the ecclesiastics, which a direct assertion of it would have brought upon them. (On a similar question, see on Joh 4:29; and on the phrase, "Son of David," see on Mat 9:27).

In this chapter, we have, I. Christ's clearing of the law of the fourth commandment concerning the sabbath-day, and vindicating it from some superstitious notions advanced by the Jewish teachers; showing that works of necessity and mercy are to be done on that day (Mat 12:1-13). II. The prudence, humility, and self-denial of our Lord Jesus in working his miracles (Mat 12:14-21). III. Christ's answer to the blasphemous cavils and calumnies of the scribes and Pharisees, who imputed his casting out devils to a compact with the devil (v. 22-37). IV. Christ's reply to a tempting demand of the scribes and Pharisees, challenging him to show them a sign from heaven (Mat 12:38-45). V. Christ's judgment about his kindred and relations (Mat 12:46-50).

12:23 Amazement was a common response to Jesus’ miracles (Mark 2:12; 6:51; Luke 2:47; 8:56; 24:22). • Could it be: The question expected a negative answer: Jesus did not fit their expectations for the Messiah, but his miracles did prompt the question.
