A hot-tempered man stirs up strife, but he who is slow to anger quiets contention. 

  Titus 3:9-11 But avoid foolish controversies, genealogies, dissensions, and quarrels about the law, for they are unprofitable and worthless. As for a person who stirs up division, after warning him once and then twice, have nothing more to do with him, knowing that such a person is warped and sinful; he is self-condemned. Proverbs 20:3 It is an honor for a man to keep aloof from strife, but every fool will be quarreling. 2 Timothy 2:23 Have nothing to do with foolish, ignorant controversies; you know that they breed quarrels. Romans 14:1-23 As for the one who is weak in faith, welcome him, but not to quarrel over opinions. One person believes he may eat anything, while the weak person eats only vegetables. Let not the one who eats despise the one who abstains, and let not the one who abstains pass judgment on the one who eats, for God has welcomed him. Who are you to pass judgment on the servant of another? It is before his own master that he stands or falls. And he will be upheld, for the Lord is able to make him stand. One person esteems one day as better than another, while another esteems all days alike. Each one should be fully convinced in his own mind. … 1 Corinthians 15:33 Do not be deceived: “Bad company ruins good morals.” Proverbs 26:17 Whoever meddles in a quarrel not his own is like one who takes a passing dog by the ears. James 4:17 So whoever knows the right thing to do and fails to do it, for him it is sin. James 4:1 What causes quarrels and what causes fights among you? Is it not this, that your passions are at war within you? Proverbs 17:14 The beginning of strife is like letting out water, so quit before the quarrel breaks out. Proverbs 21:19 It is better to live in a desert land than with a quarrelsome and fretful woman. Proverbs 15:18 A hot-tempered man stirs up strife, but he who is slow to anger quiets contention.
