But when that which is perfect is come, then that which is in part shall be done away. When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things. For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known. And now abideth faith, hope, charity, these three; but the greatest of these is charity.
1 Corinthians 13:10-13 KJV
Make no friendship with an angry man; and with a furious man thou shalt not go: Lest thou learn his ways, and get a snare to thy soul. Be not thou one of them that strike hands, or of them that are sureties for debts.
Proverbs 22:24-26 KJV
