'Roofs' in the Bible

In their streets they are girded with sackcloth; on their roofs, and in their broadways, every one howleth, melted into tears.

The burden of the Valley of Vision. What -- to thee, now, that thou hast gone up, All of thee -- to the roofs?

And their inhabitants are feeble-handed, They were broken down, and are dried up. They have been the herb of the field, And the greenness of the tender grass, Grass of the roofs, And blasted corn, before it hath risen up.
