44 Now some of them wanted to take Him, but no one laid hands on Him.
45 Then the officers came to the chief priests and Pharisees, who said to them, “Why have you not brought Him?”
46 The officers answered, “No man ever spoke like this Man!”
47 Then the Pharisees answered them, “Are you also deceived? 48 Have any of the rulers or the Pharisees believed in Him? 49 But this crowd that does not know the law is accursed.”
50 Nicodemus (he who came to Jesus by night, being one of them) said to them,
51 “Does our law judge a man before it hears him and knows what he is doing?”
52 They answered and said to him, “Are you also from Galilee? Search and look, for no prophet has arisen out of Galilee.”
53 And everyone went to his own house.
The officers sent to arrest Jesus were so impressed by His words that they couldn't bring themselves to carry out their orders.
It wasn't Jesus' miracles that impressed the officers, but His Words.
Have any rulers … (verse 47) — Surely (they said) if Jesus was really from God, we would have believed in Him. The commoners were confused because they didn't know the law and didn't know any better — or so the Pharisees claimed.
If Nicodemus believed back in John 3, he hadn't told his fellow Pharisees (verse 50).
our law (verse 52) — an accused person had a right to defend himself, to confront and cross-examine his accusers. One witness shall not rise against a man concerning any iniquity or any sin that he commits; by the mouth of two or three witnesses the matter shall be established (Deuteronomy 19:15).
no prophet has arisen out of Galilee (verse 52) — Elijah, Elisha, Amos and Jonah were all from Galilee.
And Isaiah 9:1-7 does prophecy that the Messiah will be from Galilee.
