'Shameless' in the Bible

I tell you, even though he will not get up and give him anything just because he is his friend, yet because of his persistence and boldness he will get up and give him whatever he needs.

For the time already past is [more than] enough for doing what the [unsaved] Gentiles like to do—living [unrestrained as you have done] in a course of [shameless] sensuality, lusts, drunkenness, carousing, drinking parties, and wanton idolatries.
