And when you shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh.
This desolating power is spoken of by Daniel as follows: Daniel 9:26-27 And the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined. ...and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate [margin, “desolator”].
Here is a clear prophecy of the destruction of Jerusalem by the Roman armies. The flight of the Christians of Judea to the mountains would be attended with difficulties. And their subsequent condition would be that of hardship and suffering. The Lord knew this, and gave them the instructions and warnings necessary."
