But now we find the old-established faith in Jerusalem so far undermined that it has to be supplemented by other grounds of hope. In particular there are two of these--the king and a foreign ally. The ally is mentioned first because the poet starts from the time when men still hoped that the Egyptians would espouse the cause of Israel, and come to the help of the little kingdom against the hosts of Babylon. There was much to be said in favour of this expectation. In the past Egypt had been in alliance with the people now threatened. The two great kingdoms of the Nile and the Euphrates were rivals; and the aggressive policy of Babylon had brought her into conflict with Egypt. The Pharaohs might be glad to have Israel preserved as a "buffer state." Indeed, negotiations had been carried on with that end in view. Nevertheless the dreams of deliverance built on this foundation were doomed to disappointment. The poet shows us the anxious Jews on their city towers straining their eyes till they are weary in watching for the relief that never comes. They could look down through the gap in the hills towards Bethlehem and the south country, and the dust of an army would be visible from afar in the clear Syrian atmosphere; but, alas! no distant cloud promises the approach of the deliverer. We are reminded of the siege of Lucknow; but in the hour of the Jews' great need there is no sign corresponding to the welcome music of the Scotch air that ravished the ears of the British garrison. Faithful prophets had repeatedly warned the Jews against this false ground of hope. In a former generation Isaiah had cautioned his contemporaries not to lean on "this broken reed"[256] Egypt; and at the present crisis Jeremiah had followed with similar advice, predicting the failure of the Egyptian alliance, and replying to the messengers of Zedekiah who had come to solicit the prophet's prayers: "Thus saith the Lord, the God of Israel: Thus shall ye say to the king of Judah, that sent you unto me to enquire of me; Behold, Pharaoh's army, which is come forth to help you, shall return to Egypt into their own land. And the Chaldæans shall come again, and fight against this city; and they shall take it, and burn it with fire."[257] Though regarded at the time as unpatriotic and even treasonable, this advice proved to be sound, and the predictions of the messenger of Jehovah correct. Now that we can read the events in the light of history we have no difficulty in perceiving that even as a matter of state policy the counsel of Isaiah and Jeremiah was wise and statesmanlike. Babylon was quite irresistible. Even Egypt could not stand against the powerful empire that was making itself master of the world. Besides, alliance with Egypt involved the loss of liberty, for it had to be paid for, and the weak ally of a great kingdom was no better than a tributary state. Meanwhile Israel was embroiled in quarrels from which
