'Fret' in the Bible

{A Psalm of David.} Fret not thyself because of evildoers, neither be thou envious against the workers of iniquity.

Rest in the LORD, and wait patiently for him: fret not thyself because of him who prospereth in his way, because of the man who bringeth wicked devices to pass.

Cease from anger, and forsake wrath: fret not thyself in any wise to do evil.
