11 The Jews were already out looking for him, asking around, "Where is that man?" 12 There was a lot of contentious talk about him circulating through the crowds. Some were saying, "He's a good man." But others said, "Not so. He's selling snake oil." 13 This kind of talk went on in guarded whispers because of the intimidating Jewish leaders.
14 With the Feast already half over, Jesus showed up in the Temple, teaching. 15 The Jews were impressed, but puzzled: "How does he know so much without being schooled?" 16 Jesus said, "I didn't make this up. What I teach comes from the One who sent me. 17 Anyone who wants to do his will can test this teaching and know whether it's from God or whether I'm making it up.

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.
