32 "There is another who testifies of Me, and I know that the testimony which He gives about Me is true.

John 8:13-14

13 So the Pharisees said to Him, "You are testifying about Yourself; Your testimony is not true."

12 For we are not bold to class or compare ourselves with some of those who commend themselves; but when they measure themselves by themselves and compare themselves with themselves, they are without understanding.
