Charles Ellicott Commentary Romans 10:15

"and how shall they preach, except they be sent? even as it is written, How beautiful are the feet of them that bring glad tidings of good things!" — Romans 10:15 (ASV)

The happy consequences of this preaching were already intimated by the prophet Isaiah.

Preach the gospel of peace.—These words are omitted in the group of oldest manuscripts, and should be left out in the text. The whole of the quotation is not given by St. Paul.
