Isaiah 51:2

I called him alone. — Literally, as one. If so great a nation had sprung from one man (Hebrews 11:12), so would God out of the faithful remnant once more create a people. (Comp. Ezekiel 33:24, where the exiles arc represented as boastfully inverting the argument: “Abraham was one, and we are many; therefore we shall prosper, the chances are in our favour.”)
