Isaiah 3:26 - Matthew Poole's English Annotations on the Holy Bible

Her gates; the gates of Zion or Jerusalem, which, by a figure very usual in sacred Scripture and all authors, are said to lament, to imply the great desolation of the place, that there should be no people to go out and come in by the gates, or to meet together in the gates, as they used to do. Shall sit upon the ground, like a mournful woman bewailing the loss of her husband and children.
