16 But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report?

20 But 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.
21 But to Israel he saith, All day long I have stretched forth my hands unto a disobedient and gainsaying people.
