You testify about yourself

"You are just saying these things about yourself"

your testimony is not true

The Pharisees are implying that the witness of only one person is not true because it cannot be verified. Alternate translation: "you cannot be your own witness" or "what you say about yourself may not be true" (See: rc://en/ta/man/translate/figs-explicit)
