Albert Barnes on Matthew 24:51

Shall cut him asunder. This kind of punishment was anciently practised. Sometimes it was done by the sword, sometimes by saws. It was practised among the Chaldeans, Dan 2:5, 3:29 and among the Hebrews, 2Sam 12:31, 1Sam 15:33, 1Kgs 3:25, Heb 11:37. It was also practised by the Egyptians and Romans. It is not, perhaps, here to be taken literally, but signifies that the wicked servant should be severely punished.

Hypocrites. Mt 6:2. They are spoken of here as the worst of men.

Weeping and gnashing of teeth. Mt 8:12,13. The unfaithful and wicked minister of God, who lives without expectation or fear of judgment, shall suffer the severest punishment inflicted on sinners in the world of woe.

(r) "There shall" Mt 25.30
