Synopsis of the Books of the Bible, by John Nelson Darby, [1857-62], at sacred-texts.com
The following commentary covers Chapters 5 and 6.
In the revelation given to Ezekiel Jerusalem is taken, and its population almost entirely destroyed. The dispersed remnant are pursued by the sword, and a portion only of this remnant is spared. There would be some even of this portion cast into the fire [See Note #1]. And this fire should reach to the whole house of Israel. That is to say, the judgment that should fall upon the remnant who do not perish in the city should represent the position of all Israel. It is thus that the prophet is constantly led to speak of the whole nation. For, as long as there was a remnant at Jerusalem, the nation had a place on the earth. But when the iniquitous rebellion of Zedekiah had led to the destruction of Jerusalem, this was no longer the case. But this judgment of Jerusalem contains very important elements for the understanding of all this part of the history of the people and of the dealings of God, "This is Jerusalem, saith the Lord Jehovah; I have set it in the midst of the nations and countries round about her." And instead of being a testimony in the midst of the nations, so that the house of Jehovah should have attracted them, or at least have placed them under responsibility by a true testimony to God who dwelt there-instead of this, her inhabitants had even gone beyond the idolatrous nations in wickedness. Therefore God would execute judgments upon her in the sight of all the nations-a just retribution for her sins. She should also be laid waste and made a reproach among the nations round about her; and (chap. 6) the judgment should not be confined to Jerusalem, it should be executed on all the high places, on all the mountains of Israel. Every city should be desolate, all their idols destroyed, and the people scattered. They should know that the Lord had not threatened them in vain with His judgments. The fire should reach those that were afar off as well as those that were in the land; and the land should be laid waste, and the worshippers of idols slain around their infamous gods. Nevertheless God would remember mercy in the midst of judgment; He would spare a little remnant of those who were scattered, and those who should escape should loathe themselves for the abominations they had committed. Thus Jerusalem was judged as well as the mountains of Israel, which were but too notorious for their idols and their high places.
It is thus that I understand this passage. We should imagine, from our translation, that it was some of the hairs that were cast into the fire. But in the Hebrew the pronoun is in the singular, and it is masculine as well as feminine.
