Bible verses about "fidelity" | Wesley

¹⁸ Whosoever putteth away his wife and marrieth another, committeth adultery; and whosoever marrieth her that is put away from her husband, committeth adultery.

⁴ Love suffereth long and is kind; love envieth not; love acteth not rashly, is not puffed up: ⁵ Doth not behave indecently, seeketh not her own, is not provoked, thinketh no evil; Rejoiceth not at iniquity, but rejoiceth in the truth: ⁶ Covereth all things, ⁷ believeth all things, hopeth all things, endureth all things.

⁴ Marriage is honourable in all men, and the bed undefiled: but whoremongers and adulterers God will judge.
