'Security' in the Bible

Then the five men departed, and came to La'ish, and saw the people who were there, how they dwelt in security, after the manner of the Sido'nians, quiet and unsuspecting, lacking nothing that is in the earth, and possessing wealth, and how they were far from the Sido'nians and had no dealings with any one.

If thou hast run with footmen, and they have wearied thee, how wilt thou then contend with horses? And if in a land of peace thou thinkest thyself in security, how wilt thou then do in the swelling of the Jordan?

This is the rejoicing city that dwelt in security, that said in her heart, I am, and there is none else beside me: how is she become a desolation, a couching-place for beasts! Every one that passeth by her shall hiss, shall wave his hand.
