Matthew 5:31

"It was also said, 'If any man puts away his wife, let him give her a written notice of divorce.'

"Why then," said they, "did Moses command the husband to give her 'a written notice of divorce,' and so put her away?"

Then came some of the Pharisees to Him to put Him to the proof by the question, "Has a man a right to divorce his wife whenever he chooses?"

Presently a party of Pharisees come to Him with the question--seeking to entrap Him, "May a man divorce his wife?"
