'Faithless' in the Bible

I will set no vile thing before my eyes. I hate the deeds of faithless men. They will not cling to me.

I look at the faithless with loathing, because they don't observe your word.

Jesus answered, "Faithless and perverse generation! How long will I be with you? How long will I bear with you? Bring him here to me."

Jesus answered, "Faithless and perverse generation, how long shall I be with you and bear with you? Bring your son here."

If we are faithless, he remains faithful. He can't deny himself."
