Matthäus 12:39

But he answered and said unto them--"when the people were gathered thick together" (Luk 11:29). An evil and adulterous generation--This latter expression is best explained by Jer 3:20, "Surely as a wife treacherously departeth from her husband, so have ye dealt treacherously with Me, O house of Israel, saith the Lord." For this was the relationship in which He stood to the covenant-people--"I am married unto you" (Jer 3:14). seeketh after a sign--In the eye of Jesus this class were but the spokesmen of their generation, the exponents of the reigning spirit of unbelief. and there shall no sign be given to it, but the sign of the prophet Jonas.

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).

12:39-40 To demand a sign demonstrates a lack of faith. • The sign of the prophet Jonah consisted of Jonah’s “resurrection” from the large fish after three days and three nights as well as his preaching (12:41; Luke 11:32); it was analogous to Jesus’ burial and resurrection and his preaching. Jesus was drawing a parallel between Jonah’s experience and what he himself would experience. He was not predicting an exact chronology of his death and resurrection. • Heart of the earth is a euphemism for the grave.
