'Carefree' in the Bible

So the five men left and went to Laish, and observed the people who were living there carefree, as Sidonians tend to do, in peace and quiet. There was no ruler in the land oppressing them for any reason. They were living far away from the Sidonians, and had no dealings with anyone.

When you invade, you'll meet a carefree people living in a spacious territory. God has given it into your control it's a place that lacks nothing on this earth!"

But the descendants of Dan took what Micah had made, along with the priest who had worked for him, and went to Laish, to a quiet and carefree people, and killed them with swords. Then they set fire to the city.
