Isaiah 49:18

Two things are here promised, which were to be in part accomplished in the reviving of the Jewish church after its return out of captivity, but more fully in the planting of the Christian church by the preaching of the gospel of Christ; and we may take the comfort of these promises.

It was promised (Isa 49:17) that her children should make haste; that promise is here enlarged upon, and is made very encouraging. It is promised, 1.
