Matthew Poole and continuators on Romans 15:12

12. And again Esaias saith , There shall be a root of Jesse, and he that shall rise to reign over the Gentiles, in him shall the Gentiles trust.

viz. in Isa. 11.10. See the Notes there. This is a plain Prophesie of the Conversion of the Gentiles; their being received to Mercy, is implied in the former Testimonies, but here it is expressed. The Son of David (the Saviour) shall rise and spring out of Jesse his Root, and Reign over the Gentiles by his Word and Spirit. He shall gather them by the Preaching of his Cross, as by an ensign, and they, as it is in the Prophet, shall seek to him; or as it is here, shall trust or hope in him. The Apostle, as he is wont, doth follow the LXX. which makes some little variation from the Hebrew Text; but it is rather in sound than in sence. You have other Prophesies and Promises of the Gentiles Mercy, as Isa. 42.1, 6. and 49.22. & 54.3. and 60.3, 5. But the Apostle thought, that these he had mentioned were sufficient for his purpose.
