Question on John 7: 1-5

John 7:1-5 ESV
(1) After this Jesus went about in Galilee. He would not go about in Judea, because the Jews were seeking to kill him.
(2) Now the Jews' Feast of Booths was at hand.
(3) So his brothers said to him, "Leave here and go to Judea, that your disciples also may see the works you are doing.
(4) For no one works in secret if he seeks to be known openly. If you do these things, show yourself to the world."
(5) For not even his brothers believed in him.

Now I want to ask you. What about the first five verses clues you in that his brothers do not believe in him?

Hmm. perhaps in this translation it is a bit more clear. I used the NASB for my devotional time. In that one it is not so clear.

Is it clear to you? Respond with an answer if you like. I'd like to read it.
