4 Bible Verses about Fretting

As for the folly of humankind, its way leads to ruin, and against Yahweh his heart will rage.

Do not fret because of evildoers; do not be envious of doers of wickedness. For like the grass they will dry up quickly, and like green vegetation they will wither.

Be quiet before Yahweh and wait for him. Do not fret about one who succeeds [in] his way, about a man making plots. Refrain from anger and forsake wrath. Do not fret; [it] only brings evil.

Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God.
