Ephesians 4:26-27 (NKJV)
26 “Be angry, and do not sin”: do not let the sun go down on your wrath, 27 nor give place to the devil.
Ephesians 4:31-32N (NKJV)
31 Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you, with all malice. 32 And be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you.
James 3:8-12 (NKJV)
8 But no man can tame the tongue. It is an unruly evil, full of deadly poison. 9 With it we bless our God and Father, and with it we curse men, who have been made in the similitude of God. 10 Out of the same mouth proceed blessing and cursing. My brethren, these things ought not to be so. 11 Does a spring send forth fresh water and bitter from the same opening? 12 Can a fig tree, my brethren, bear olives, or a grapevine bear figs? Thus no spring yields both salt water and fresh.
