In scripture, `{{H4571}}` is used to contrast the security of the righteous with the instability of the wicked.

Conversely, the term is used in a curse against enemies, asking God to "make their loins continually to **shake**" [[Psalms 69:23]], and it describes the one who is "ready to **slip** with his feet" [[Job 12:5]].
