'Unholy' in the Bible

For the husband who has not faith is made holy through his Christian wife, and the wife who is not a Christian is made holy through the brother: if not, your children would be unholy, but now are they holy.

With the knowledge that the law is made, not for the upright man, but for those who have no respect for law and order, for evil men and sinners, for the unholy and those who have no religion, for those who put their fathers or mothers to death, for takers of life,

But will not the man by whom the Son of God has been crushed under foot, and the blood of the agreement with which he was washed clean has been taken as an unholy thing, and who has had no respect for the Spirit of grace, be judged bad enough for a very much worse punishment?

And he took his place on the sand of the sea. And I saw a beast coming up out of the sea, having ten horns and seven heads, and on his horns ten crowns, and on his heads unholy names.
