John 7:3

His brethren said--(See on Mat 13:54-56). Depart . . . into Judea, &c.--In Joh 7:5 this speech is ascribed to their unbelief. But as they were in the "upper room" among the one hundred and twenty disciples who waited for the descent of the Spirit after the Lord's ascension (Act 1:14), they seem to have had their prejudices removed, perhaps after His resurrection. Indeed here their language is more that of strong prejudice and suspicion (such as near relatives, even the best, too frequently show in such cases), than from unbelief. There was also, probably, a tincture of vanity in it. "Thou hast many disciples in Judea; here in Galilee they are fast dropping off; it is not like one who advances the claims Thou dost to linger so long here, away from the city of our solemnities, where surely 'the kingdom of our father David' is to be set up: 'seeking,' as Thou dost, 'to be known openly,' those miracles of Thine ought not to be confined to this distant corner, but submitted at headquarters to the inspection of 'the world.'" (See Psa 69:8, "I am become a stranger to my brethren, an alien unto my mother's children!")

In this chapter we have, I. Christ's declining for some time to appear publicly in Judea (Joh 7:1). II. His design to go up to Jerusalem at the feast of tabernacles, and his discourse with his kindred in Galilee concerning his going up to this feast (Joh 7:2-13). III. His preaching publicly in the temple at that feast. 1. In the midst of the feast (Joh 7:14, Joh 7:15). We have his discourse with the Jews, (1.) Concerning his doctrine (Joh 7:16-18). (2.) Concerning the crime of sabbath-breaking laid to his charge (Joh 7:19-24). (3.) Concerning himself, both whence he came and whither he was going (Joh 7:25-36). 2. On the last day of he feast. (1.) His gracious invitation to poor souls to come to him (Joh 7:37-39). (2.) The reception that it met with. [1.] Many of the people disputed about it (Joh 7:40-44). [2.] The chief priests would have brought him into trouble for it, but were first disappointed by their officers (Joh 7:45-49) and then silenced by one of their own court (Joh 7:50-53).

7:3-5 Jesus’ brothers (see also Mark 3:31) reminded him of his religious obligation to celebrate the festival. Their words were cynical because at this time they didn’t believe in him (John 7:5).
