John 9:30

The man answered, Herein is a marvellous thing, that ye know not from whence he is, and yet he hath opened mine eyes--He had no need to say another word; but waxing bolder in defense of his Benefactor, and his views brightening by the very courage which it demanded, he puts it to them how they could pretend inability to tell whether one who opened the eyes of a man born blind was "of God" or "a sinner"--from above or from beneath--and proceeds to argue the case with remarkable power. So irresistible was his argument that their rage burst forth in a speech of intense Pharisaism, "Thou wast altogether born in sins, and dost thou teach us?"--thou, a base-born, uneducated, impudent youth, teach us, the trained, constituted, recognized guides of the people in the things of God! Out upon thee!

After Christ's departure out of the temple, in the close of the foregoing chapter, and before this happened which is recorded in this chapter, he had been for some time abroad in the country, it is supposed about two or three months; in which interval of time Dr. Lightfoot and other harmonists place all the passages that occur from Luk 10:17 to Luk 13:17. What is recorded in ch. 7 and 8 was at the feast of tabernacles, in September; what is recorded in this and the following chapter was at the feast of dedication in December, Joh 10:22. Mr. Clark and others place this immediately after the foregoing chapter. In this chapter we have, I. The miraculous cure of a man that was born blind (Joh 9:1-7). II. The discourses which were occasioned by it. 1. A discourse of the neighbours among themselves, and with the man (Joh 9:8-12). 2. Between the Pharisees and the man (v. 13-34). 3. Between Christ and the poor man (Joh 9:35-38). 4. Between Christ and the Pharisees (Joh 9:39 to the end).

9:30 The Jewish leaders did not know where Jesus came from. The man’s astonishment was understandable—a healing like this was unprecedented. Jesus’ works confirmed his origin as from God. Once his true identity was known, belief and discipleship should have followed, but the Jewish leaders were willfully blind.
