Luke 16:18
1 Corinthians 13:4-7
4 Love is so patient and so kind; love never boils with jealousy; it never boasts, is never puffed with pride;
5 It does not act with rudeness, or insist upon its rights; it never gets provoked, it never harbors evil thoughts;
6 Is never glad when wrong is done, but always glad when truth prevails;
7 It bears up under anything; it exercises faith in everything; it keeps up hope in everything; it gives us power to endure in anything.
Hebrews 13:4
4 Marriage must be held in honor by all, and the marriage relations kept sacred. Persons who are sexually vicious and immoral God will punish.
