'Perverse Generation' in the Bible

And he said, I will hide my face from them, I will see what their end shall be: for they are a very perverse generation, children in whom is no faith.

Then Jesus answered and said, O faithless and perverse generation, how long shall I be with you? how long shall I endure you? bring him here to me.

And Jesus answering said, O faithless and perverse generation, how long shall I be with you, and bear with you? Bring your son here.
