5 All this argument have I written to you, because the Jews pride themselves, (saying), “It has been covenanted to us, that we shall be gathered.” For if Sodom, whose iniquity was not so great as that of Jerusalem, is not as yet inhabited, and if we say thus, that it will not be restored for ever, how shall Jerusalem be restored, whose iniquity is greater than that of Sodom and her daughters? As for Sodom God has not had mercy on her for two thousand two hundred and seventy-six years; and shall we say that He will have mercy on Jerusalem?
For up to the present there are but three hundred and ninety-five years from the day that she was laid waste, according to the calculation that has been written above. But as to this that he said, Sodom and her daughters shall be possessed as of old, and with regard to Jerusalem he said, You and your daughters shall become as of old, this is the force of the passage; that they shall not be inhabited for ever; for the Lord also thus cursed the land against which He was angry:— It shall not be sown, nor shall it produce, nor shall any herb spring up in it, but it shall be like Sodom and Gomorrha, against which the Lord was angry and towards which He was not appeased. Therefore be sure, my hearer, that Sodom and her daughters shall not be inhabited for ever; but they shall be as of old, namely, as in that time when they were not as yet inhabited, and as in the time when the Lord was angry with them and was not appeased towards them.
And Jerusalem and her daughters shall be as of old, (that is) as in the former time when the mountain of the Amorites lay in desolation, whereon Abraham built the altar, when he bound upon it Isaac his son; and as it was desolate when David bought the threshing-floor from Araunah the Jebusite, and built there the altar. For consider and see that this mountain whereon Abraham offered his son is the mountain of Jebus, which is Jerusalem. And this place of the threshing-floor that David bought of Araunah is that whereon the Temple was built.
Thus Jerusalem shall be in desolation as of old. And consider that when Ezekiel prophesied this passage, Jerusalem still was sitting in her greatness, and those who were in her were rebelling against the King of Babylon. And that which the Prophet spoke, he said in wrath and reproach against Jerusalem.
