Job 27:4

my lips will not speak unjustly,
and my tongue will not utter deceit.

Would you testify unjustly on God’s behalf
or speak deceitfully for Him?

But now, please look at me;
would I lie to your face?

Would I lie about my case?
My wound is incurable,
though I am without transgression.”

You’ve never known Him, but I know Him. If I were to say I don’t know Him, I would be a liar like you. But I do know Him, and I keep His word.

As the truth of Christ is in me, this boasting of mine will not be stopped in the regions of Achaia.
