Matthew 23:22

And he that shall swear by heaven,.... As the Jews were wont to do in common, but did not look upon such an oath as obligatory on them; See Gill on Mat 5:34, though such an one sweareth by the throne of God; for heaven is God's throne, where he sits, and, in an eminent manner, displays the glory of his majesty: and by him that sitteth thereon, by God himself.

The throne of God - Heaven is his throne, Mat 5:34. It is so called as being the place where he sits in glory. Jesus says, here, that all who swear at all do, in fact, swear by God, or the oath is good for nothing. To swear by an altar, a gift, or a temple is of no force unless it be meant to appeal to God himself. The essential thing in an oath is calling God to witness our sincerity. If a real oath is taken, therefore, God is appealed to.

We have in these verses the charges of our Lord against the Jewish teachers, ranged under eight heads. Standing in the midst of the temple, with a listening crowd around him, he publicly denounces the main errors of the scribes and the Pharisees, in unsparing terms. Eight times he uses the solemn expression, “Woe unto you;” seven times he calls them “hypocrites;” twice he speaks of them as “blind guides”—twice as “fools and blind”—once as “serpents! And a generation of vipers!” Let us mark that language well. It teaches a solemn lesson.

And a generation of vipers!” Let us mark that language well. It teaches a solemn lesson. It shows how utterly abominable the spirit of the scribes and the Pharisees is in God’s sight, in whatever form it may be found. Let us glance shortly at the eight charges which our Lord brings forward, and then seek to draw from the whole passage some general instruction. The first “woe” in the list is directed against the systematic opposition of the scribes and Pharisees to the progress of the Gospel. They “shut up the kingdom of heaven;” they would neither go in themselves, nor suffer others go in. They rejected the warning voice of John the Baptist; they refused to acknowledge Jesus when he appeared among them as the Messiah; they tried to keep back Jewish inquirers. They would not believe the Gospel themselves, and they did all in their power to prevent others believing it: this was a great sin. The second “woe” in the list is directed against the covetousness and self-aggrandizing spirit of the scribes and Pharisees. They “devour widows’ houses and for a pretence made long prayer.” They imposed on the credulity of weak and unprotected women by an affection of great devoutness, until they were regarded as their spiritual directors. They scrupled not to abuse the influence thus unrighteously obtained to their own temporal advantage, and, in a word, to make money by their religion: this, again, was a great sin.
