Psalm 37:7-9 (NKJV)
7Rest in the LORD, and wait patiently for Him;
Do not fret because of him who prospers in his way,
Because of the man who brings wicked schemes to pass.
8Cease from anger, and forsake wrath; Do not fret--it only causes harm.
9For evildoers shall be cut off; But those who wait on the LORD, They shall inherit the earth.
