(11-12) And the Pharisees came forth.--See Notes on Matthew 16:1-4. St. Mark, it may be noted, docs not mention the presence of the Pharisees, and gives only part of our Lord's answer. On the other and, he characteristically describes the "sighing deeply in spirit" in Mark 8:12, which St. Matthew does not give.

Verse 11. - And the Pharisees came forth - St. Matthew (Matthew 16:1) says that the Sadducees came with them - and began to question with him, seeking of him a sign from heaven, tempting him. They had already asked for a sign from heaven (Matthew 12:38); but now this miracle gives them occasion to ask again. For when they saw how greatly it was extolled by the multitudes who had benefited by it, it was easy for them to urge that it was an earthly sign, and might have been wrought by him who is called "the God of this world;" and so they insinuated that he had wrought this miracle as well as his other miracles by the power of Satan. Therefore they seek a sign from heaven, that he who dwells in heaven might thus bear witness that he came from God, and that his doctrine was Divine; the Pharisees probably meant that if he did this they would believe in him as the Messiah, and lead the people to the same faith. The Sadducees, who were practically atheists, thought that no sign could be given from heaven by God, seeing that in their opinion it was doubtful whether there was any God to give it.

8:11-21 Obstinate unbelief will have something to say, though ever so unreasonable. Christ refused to answer their demand. If they will not be convinced, they shall not. Alas! what cause we have to lament for those around us, who destroy themselves and others by their perverse and obstinate unbelief, and enmity to the gospel! When we forget the works of God, and distrust him, we should chide ourselves severely, as Christ here reproves his disciples. How is it that we so often mistake his meaning, disregard his warnings, and distrust his providence?And the Pharisees came forth,.... Out of their houses; who dwelt in the coasts of Magdala, and parts of Dalmanutha, and came to Jesus, hearing of his being arrived in their neighbourhood:

and began to question with him; or to dispute with him, it being their manner to carry on disputations by questions and answers. The Persic version has the question they put, and about which they disputed, "if thou art the Christ"; in proof of which they required a sign:

seeking of him a sign from heaven, tempting him; See Gill on Matthew 16:1.
