'Perverted' in the Bible

And Jesus answering said, O unbelieving and perverted generation, how long shall I be with you? how long shall I bear with you? Bring him here to me.

And Jesus answering said, O unbelieving and perverted generation, how long shall I be with you and suffer you? Bring hither thy son.

and from among your own selves shall rise up men speaking perverted things to draw away the disciples after them.

that ye may be harmless and simple, irreproachable children of God in the midst of a crooked and perverted generation; among whom ye appear as lights in the world,

knowing that such a one is perverted, and sins, being self-condemned.
