Contradiction with Matthew 19:9
This verse allows divorce for reasons of sexual immorality, contradicting the situation in 1 Samuel 30:5, where mention is made of David's wives and no grounds for divorce are provided.
Matthew 19:9: And I say unto you, Whosoever shall put away his wife, except [it be] for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery.
Contradiction with Deuteronomy 24:1
This verse provides a scenario where a man can divorce his wife, contrasting 1 Samuel 30:5, which suggests no dissolution of marriage despite circumstances.
Deuteronomy 24:1: When a man hath taken a wife, and married her, and it come to pass that she find no favour in his eyes, because he hath found some uncleanness in her: then let him write her a bill of divorcement, and give [it] in her hand, and send her out of his house. [some...: Heb. matter of nakedness] [divorcement: Heb. cutting off]
