Comentário sobre Isaías 22:1

the Valley of Vision This is Jerusalem, the valley concerning which most prophecies were prophesied.

The valley of vision. Jerusalem, the centre of all prophecies.

that all of you have gone up to the rooftops When an army comes upon them, they go up to their roofs to see the army and to fight. Our Rabbis, however, explained this concerning the priests who went up to the roof of the Temple with the keys of the forecourt in their hands, as is stated in the Tractate Taanith (29a). The Midrash Aggadah, however, states that they, (the people of Jerusalem,) were haughty. (This is found) in Lamentations Rabbah (Int. 24).

Thou art wholly gone up to the house-tops. Some think, they went up in order to offer incense to the host of heaven, but my opinion is, that they went up in order to see the force that besieged Jerusalem, as is generally done under such circumstances.
