<p>15:11 <i>And again: Praise the Lord all you Gentiles, and let all the peoples praise Him- </i>This quotation from Ps. 117:1 is understood as putting &quot;the peoples&quot; in parallel with &quot;all you Gentiles&quot;. The &quot;peoples&quot; were the tribes of Israel, and they along with &quot;all the Gentiles&quot; would praise Yahweh. The writer looked forward to a time when the Gentiles along with Israel would unite in praise of Israel's God. I suggest this because the other quotations here in Rom. 15 parallel the Gentiles with Israel. And this was Paul's context here- Jew and Gentile should praise the Lord together in the church at Rome. &quot;All the Gentiles&quot; is defined in Acts 15:17 as &quot;all the Gentiles upon whom My Name is called&quot;. The language of all the world or all the Gentiles refers not to every single person, but to all those who have believed in Christ.</p>
