18 whoever repudiates his wife, and marries another, is an adulterer. and he that marries her, that is repudiated by her husband, is an adulterer.
Bible verses about "fidelity" | Mace
Luke 16:18
1 Corinthians 13:4-7
4 Social affection is patient, is kind; is a stranger to envy; is not insolently vain, nor arrogant: does not behave indecently,
5 is not self-interested, is not easily provoked, nor suspects any ill;
6 it does not countenance injustice, but smiles upon virtue;
7 it excuses all things, believes what is favourable, hopes for the best, and suffers the worst.
Hebrews 13:4
4 Marriage is every where honourable, and that state is innocent: but the licentious and adulterers God will punish.
