But they that wait on the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary…
There was a real climax in the prophet's statement. And its application, in his thought, was to the return of the exiles from Babylon to Jerusalem. God's helpfulness would be adequate to their needs in all the stages of their return. In the first flush of joy, and in the first flights of eager anticipation, "on which we see them rising in the psalms of redemption as on the wings of an eagle"; again, in the rush and excitement of their hurried departure, the running to and fro in hasty and exhausting preparation; but finally, when they wanted it most, in the long tramp, tramp, tramp of those seven hundred weary miles, day after day, week after week, when their pace must be adapted to those of the heavily-laden beasts of burden, and of the little ones whose strength would often fail and who would need to be lifted up and carried in the father's arms. How often on that tiresome journey would the sweet music of the prophet's words return to their memory, "they shall walk and not faint." Then it was that their trust in Jehovah would be put fully to the proof. It was in the walking and not in the flying that their faith would triumph.
