'Ease' in the Bible

In that place, those who once were prisoners will be at ease together; they won't hear the voice of oppressors.

I will not be at ease; I will not be quiet; I will not rest; because trouble has arrived."

For I've said, "My bed will comfort me; my couch will ease my burdens while I complain.'

"He tore me apart when I was at ease; grabbing me by my neck, he shook me to pieces then he really made me his target.
