'Fret' in the Bible

Do not be anxious or worried about anything, but in everything [every circumstance and situation] by prayer and petition with thanksgiving, continue to make your [specific] requests known to God.

Fathers, do not provoke or irritate or exasperate your children [with demands that are trivial or unreasonable or humiliating or abusive; nor by favoritism or indifference; treat them tenderly with lovingkindness], so they will not lose heart and become discouraged or unmotivated [with their spirits broken].
