They shall come and shall declare his righteousness Unto a people that shall be born, that he hath done it.

They will come and make his righteousness clear to a people of the future because he has done this.

Θελουσιν ελθει και αναγγειλει την δικαιοσυνην αυτου, προς λαον, οστις μελλει να γεννηθη· διοτι αυτος εκαμε τουτο.

They shall come, and shall declare his righteousness unto a people that shall be born, that he hath done this.
