'Careless' in the Bible

Behold, this was the iniquity of thy sister Sodom: pride, fulness of bread, and careless ease was in her and in her daughters, but she did not strengthen the hand of the poor and needy.

The sound of a carefree crowd was with her; and drunkards were brought from the wilderness with men of a common sort, who put bracelets on the hands of the women (both sisters) and beautiful crowns on their heads.

In that day shall messengers go forth from me in ships to make the careless Ethiopians afraid, and great pain shall come upon them, as in the day of Egypt: for, lo, it cometh.
