16 A curse is on you, blind guides, who say, Whoever takes an oath by the Temple, it is nothing; but whoever takes an oath by the gold of the Temple, he is responsible. 17 You foolish ones and blind: which is greater, the gold, or the Temple which makes the gold holy? 18 And, Whoever takes an oath by the altar, it is nothing; but whoever takes an oath by the offering which is on it, he is responsible. 19 You blind ones: which is greater, the offering, or the altar which makes the offering holy? 20 He, then, who takes an oath by the altar, takes it by the altar and by all things on it. 21 And he who takes an oath by the Temple, takes it by the Temple and by him whose house it is. 22 And he who takes an oath by heaven, takes it by the seat of God, and by him who is seated on it. 23 A curse is on you, scribes and Pharisees, false ones! for you make men give a tenth of all sorts of sweet-smelling plants, but you give no thought to the more important things of the law, righteousness, and mercy, and faith; but it is right for you to do these, and not to let the others be undone.
Matthew Henry's Commentary on Matthew 23:16-23
Commentary on Matthew 23:13-33
(Read Matthew 23:13-33)
The scribes and Pharisees were enemies to the gospel of Christ, and therefore to the salvation of the souls of men. It is bad to keep away from Christ ourselves, but worse also to keep others from him. Yet it is no new thing for the show and form of godliness to be made a cloak to the greatest enormities. But dissembled piety will be reckoned double iniquity. They were very busy to turn souls to be of their party. Not for the glory of God and the good of souls, but that they might have the credit and advantage of making converts. Gain being their godliness, by a thousand devices they made religion give way to their worldly interests. They were very strict and precise in smaller matters of the law, but careless and loose in weightier matters. It is not the scrupling a little sin that Christ here reproves; if it be a sin, though but a gnat, it must be strained out; but the doing that, and then swallowing a camel, or, committing a greater sin. While they would seem to be godly, they were neither sober nor righteous. We are really, what we are inwardly. Outward motives may keep the outside clean, while the inside is filthy; but if the heart and spirit be made new, there will be newness of life; here we must begin with ourselves. The righteousness of the scribes and Pharisees was like the ornaments of a grave, or dressing up a dead body, only for show. The deceitfulness of sinners' hearts appears in that they go down the streams of the sins of their own day, while they fancy that they should have opposed the sins of former days. We sometimes think, if we had lived when Christ was upon earth, that we should not have despised and rejected him, as men then did; yet Christ in his Spirit, in his word, in his ministers, is still no better treated. And it is just with God to give those up to their hearts' lusts, who obstinately persist in gratifying them. Christ gives men their true characters.
