11 the Jews, therefore, were seeking him, in the feast, and said, 'Where is that one?' 12 and there was much murmuring about him among the multitudes, some indeed said—'He is good;' and others said, 'No, but he leadeth astray the multitude;' 13 no one, however, was speaking freely about him, through fear of the Jews.
14 And it being now the middle of the feast, Jesus went up to the temple, and he was teaching, 15 and the Jews were wondering, saying, 'How hath this one known letters—not having learned?' 16 Jesus answered them and said, 'My teaching is not mine, but His who sent me; 17 if any one may will to do His will, he shall know concerning the teaching, whether it is of God, or—I do speak from myself.

Commentary on John 7:1-13
(Read John 7:1-13)
The brethren or kinsmen of Jesus were disgusted, when they found there was no prospect of worldly advantages from him. Ungodly men sometimes undertake to counsel those employed in the work of God; but they only advise what appears likely to promote present advantages. The people differed about his doctrine and miracles, while those who favoured him, dared not openly to avow their sentiments. Those who count the preachers of the gospel to be deceivers, speak out, while many who favour them, fear to get reproach by avowing regard for them.
Commentary on John 7:14-24
(Read John 7:14-24)
Every faithful minister may humbly adopt Christ's words. His doctrine is not his own finding out, but is from God's word, through the teaching of his Spirit. And amidst the disputes which disturb the world, if any man, of any nation, seeks to do the will of God, he shall know whether the doctrine is of God, or whether men speak of themselves. Only those who hate the truth shall be given up to errors which will be fatal. Surely it was as agreeable to the design of the sabbath to restore health to the afflicted, as to administer an outward rite. Jesus told them to decide on his conduct according to the spiritual import of the Divine law. We must not judge concerning any by their outward appearance, but by their worth, and by the gifts and graces of God's Spirit in them.
