Matthew Poole and continuators on Isaiah 51:5

5 My righteousness is near: my salvation is gone forth , and mine arms shall judg the people : the isles shall wait upon me , and on mine arm shall they trust.

My Salvation, as it is expounded in the next clause, the Redemption of all my people, both Jews and Gentiles, which is the effect of his Righteousness, either his Justice, or his Faithfulness, or his Mercy & Goodness, for all these are called by the name of Righteousness in Scripture, and all these contributed to the work of Mans Redemption.

Shall shortly go forth: my secret and eternal purpose of saving my People shall speedily be fulfilled.

Either 1. Shall destroy those People who obstruct or oppose this work. Or rather 2. Shall subdue the Gentiles to mine Authority, and rule them by my Word and Spirit, which agrees best with the following clause.

The remote Countries of the Gentiles, as Isa. 41. 1. & 42. 4. and elsewhere.

Shall confidently expect and hope for this promised Righteousness and Salvation from me, and from me only, and not from Idols, as they have none, nor by any other way.
