15And 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! 16But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report? 17So then faith cometh by hearing, and hearing by the word of God. 18But I say, Have they not heard? Yes verily, their sound went into all the earth, and their words unto the ends of the world.19But I say, Did not Israel know? First Moses saith, I will provoke you to jealousy by them that are no people, and by a foolish nation I will anger you. 20But Esaias is very bold, and saith, I was found of them that sought me not; I was made manifest unto them that asked not after me. 21But to Israel he saith, All day long I have stretched forth my hands unto a disobedient and gainsaying people.
