“The Pharisees heard that the people murmured such things concerning him; and the Pharisees and the chief priests sent officers to take him.”
King James Version (KJV)
7:30 His hour - The time of his suffering.
7:33 Then said Jesus - Continuing his discourse (from #John 7:29|) which they had interrupted.
7:34 Ye shall seek me - Whom ye now despise. These words are, as it were, the text which is commented upon in this and the following chapter. Where I am - Christ's so frequently saying while on earth, where I am, when he spake of his being in heaven, intimates his perpetual presence there in his Divine nature: though his going thither was a future thing, with regard to his human nature.
Joh 7:32 The Pharisees heard. The bitterest enemies of Christ. When they heard that the people were believing, they thought it time for action, so the Pharisees and chief priests, that is, the Sanhedrin, sent officers to take him. This was an official act, the "first" official attempt of the Sanhedrin to take Jesus. They had purposed it before, but had not taken action.
