wrongly ... wrong

These words refer to moral wrong, like blasphemy, not to mere mistakes about facts.

testify about the wrong

"tell me what I said that was wrong"

if rightly, why do you hit me?

This remark appears in the form of a question to add emphasis to what Jesus is saying. Alternate translation: "if I said only what was right, you should not be hitting me!" (See: rc://en/ta/man/jit/figs-rquestion)
