John 7:18

16 “My teaching is not My own,” Jesus replied. “It comes from Him who sent Me.

17 If anyone desires to do His will, he will know whether My teaching is from God or whether I speak on My own.

He who speaks on his own authority seeks his own glory, but He who seeks the glory of the One who sent Him is a man of truth; in Him there is no falsehood.

19 Has not Moses given you the law? Yet not one of you keeps it. Why are you trying to kill Me?”

20 “You have a demon,” the crowd replied. “Who is trying to kill You?”

Do read the surrounding verses too, because the context often says more than a single verse.
