John Gill's Exposition of the Whole Bible
Ezekiel 7:16
But they that escape of them shall escape,.... Some few should escape the pestilence, famine, and sword, and flee to the mountains, where they should live a very miserable and uncomfortable life; so that this is no contradiction to the wrath of God being upon the whole multitude, Ezekiel 7:12; as it follows:
and shall be on the mountains; whither they shall flee, when the city is broken up and taken; and so the Syriac version reads it, in connection with the preceding words, "and they that escape of them shall escape to the mountains"; barren and desert places, where they shall find no subsistence, nor have any agreeable company and conversation, but live in solitude and distress:
like doves of the valleys, all of them mourning, everyone for his iniquity: like doves that live in valleys, or gather together there, and hide themselves in the holes of the rocks, on the sides of the valleys, from birds of prey; or are so called, to distinguish them from wild doves, which, when they have lost their mates, make a very mournful noise, though not loud and clamorous. So those Jews that escaped, being in such an uncomfortable condition, turned out of house and home, and deprived of their substance, should lament their fate; not in loud cries, lest they should be heard by the enemy and taken, but in secret sighs, and in a mournful tone; acknowledging to God, and to one another, their sins; they now became sensible of, which brought these calamities upon them. So God's people, the remnant according to the election of grace, who "escape" the general ruin sin has brought on mankind, are for the most part "upon the mountains", in an afflicted and persecuted state; they are like "doves" for their harmlessness, amiableness, cleanness, modesty chastity, sociableness, and timorous disposition; and like doves "of the valleys", in a low estate, through corruption, temptation, desertion, affliction, and persecution; and "mourn" over their own "iniquity", the sin of their nature, their unbelief and various transgressions being committed against a God of love, contrary to his grace, grieving to his Spirit, and dishonourable to his Gospel; and being what break their bereave them of comfort, and deprive them of communion with God.
