John 7:1-9 — After these things Jesus walked in Galilee: for He would not walk in Jewry, because the Jews sought to kill Him.
Now the Jew's feast of tabernacles was at hand.
His brethren therefore said unto Him, Depart hence, and go into Judaea, that Thy disciples also may see the works that Thou doest.
For there is no man that doeth any thing in secret, and he himself seeketh to be known openly. If Thou do these things, shew Thyself to the world.
For neither did His brethren believe in Him.
Then Jesus said unto them, My time is not yet come: but your time is alway ready.
The world cannot hate you; but Me it hateth, because I testify of it, that the works thereof are evil.
Go ye up unto this feast: I go not up yet unto this feast: for My time is not yet full come.
When He had said these words unto them, He abode still in Galilee.
Jesus walked — manifesting Himself publicly (1:36; 6:19; 10:23; 11:54).
Brethren (Matthew 13:55) — blood relations, perhaps sons of Mary and Joseph after Jesus was born. At this time, they did not believe Jesus was the Messiah, but by Acts 1:14, they did.
They urged Him, perhaps sarcastically, to show Himself.
The world did not hate them because they were still of the world (John 15:9).
In Leviticus 23, Tabernacles is listed with the feasts of Jehovah. Now it is just called a feast of the Jews. The true meaning of it had been lost, so the Lord didn't associate His name with it.
Tabernacles — celebration of harvest, in the month of Tishri (our mid-September to mid-October)
His brothers said "No one who wants to be known acts in secret." Were they challenging Him to prove Himself?
From here on in John, Jesus is seen as the suffering Messiah. Here He suffers the unbelief of His own brothers.
Jesus knew the Jews sought to kill Him, so He didn't go up, not out of fear but because it wasn't time for Him to die.
