Here, I. The people of God express the deep concern they had for the ruins of the temple, more than for any other of their calamities; the interests of God's house lay nearer their hearts than those of their own (v. 17, 18): For this our heart is faint, and sinks under the load of its own heaviness; for these things our eyes are dim, and our sight is gone, as is usual in a deliquium, or fainting fit. "It is because of the mountain of Zion, which is desolate, the holy mountain, and the temple built upon that mountain. For other desolations our hearts grieve and our eyes weep; but for this our hearts faint and our eyes are dim." Note, Nothing lies so heavily upon the spirits of good people as that which threatens the ruin of religion or weakens its interests; and it is a comfort if we can appeal to God that that afflicts us more than any temporal affliction to ourselves. "The people have polluted the mountain of Zion with their sins, and therefore God has justly made it desolate, to such a degree that the foxes walk upon it as freely and commonly as they do in the woods." It is sad indeed when the mountain of Zion has become a portion for foxes (Ps. lxiii. 10); but sin had first made it so, Ezek. xiii. 4.
