Romans 10:14-15

Young's Literal Translation

¹⁴ How then shall they call upon [him] in whom they did not believe? and how shall they believe [on him] of whom they did not hear? and how shall they hear apart from one preaching?

¹⁵ and how shall they preach, if they may not be sent? according as it hath been written, `How beautiful the feet of those proclaiming good tidings of peace, of those proclaiming good tidings of the good things!'
