And I will do in thee that which I have not done, and whereunto I will not do any more the like, because of all thine abominations.

Wesley's Notes

5:9 Not done - Though the old world perished by water, and Sodom by fire, yet neither one or other was so lingering a death.

Jamieson-Fausset-Brown Bible Commentary

9. See on [1022]Eze 5:7.

that which I have not done-worse than any former judgments (La 4:6; Da 9:12). The prophecy includes the destruction of Jerusalem by the Romans, and the final one by Antichrist (Zec 13:8, 9; 14:2), as well as that by Nebuchadnezzar. Their doom of evil was not exhausted by the Chaldean conquest. There was to be a germinating evil in their destiny, because there would be, as the Lord foresaw, a germinating evil in their character. As God connected Himself peculiarly with Israel, so there was to be a peculiar manifestation of God's wrath against sin in their case [Fairbairn]. The higher the privileges the greater the punishment in the case of abuse of them. When God's greatest favor, the gospel, was given, and was abused by them, then "the wrath was to come on them to the uttermost" (1Th 2:16).

Matthew Henry's Concise Commentary

5:5-17 The sentence passed upon Jerusalem is very dreadful, the manner of expression makes it still more so. Who is able to stand in God's sight when he is angry? Those who live and die impenitent, will perish for ever unpitied; there is a day coming when the Lord will not spare. Let not persons or churches, who change the Lord's statutes, expect to escape the doom of Jerusalem. Let us endeavour to adorn the doctrine of God our Saviour in all things. Sooner or later God's word will prove itself true.
