Matthew Poole and continuators on Romans 10:15

15. And how shall they preach, except they be sent ? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things.

Viz. Immediately by God or Christ; or the Prophets, and the Apostles, vid. Gal. 1.1. Or mediately by Men, i. e. By such as have Authority from Christ, to Separarate and Ordain Others to this Work; without this orderly Mission or Ordination, How can they Preach, saith the Apostle? i. e. How can they do it Duely or Profitably, or in the Name, and by the Authority of Christ? For otherwise, there were, and still are, those that Run before they are sent, Ier. 23.21.

Their Arrival or Approach. The Persons of such are meant, though their Feet be named, because they carried them up and down to do this Work. The Scripture referred to, is found in Isa. 52.7. The Apostle here leaveth the Septuagint, and followeth the Hebrew Text: Yet he doth not Cite the Place in all Points, as the Prophet hath it. He leaveth out some words, as (upon the Mountains) which had respect to the Situation of Ierusalem; and he changeth the Number, turning the Singular into the Plural. Obj. But the Text in Isaiah speaks of such a Messenger, as was sent to Publish the Deliverance of the Iews, from the Bondage of the Assyrians. A. Though that be granted, it is applied and accommodated aptly enough to the Preaching of Peace and Salvation by Christ; because that Deliverance (as all other Temporal Deliverances) had its Foundation in the Redemption purchased by Christ.
