3 Some Pharisees came to him to test him. They asked, “Is it lawful for a man to divorce his wife for any and every reason?”
4“Haven’t you read,” he replied, “that at the beginning the Creator ‘made them male and female,’ a 5and said, ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh’ b ? 6So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.”
7“Why then,” they asked, “did Moses command that a man give his wife a certificate of divorce and send her away?”
8Jesus replied, “Moses permitted you to divorce your wives because your hearts were hard. But it was not this way from the beginning. 9I tell you that anyone who divorces his wife, except for sexual immorality, and marries another woman commits adultery.”
Jesus did not say that the Pharisees misread Moses' command. They might or might not have.
1 Then Jesus said to the crowds and to his disciples: 2“The teachers of the law and the Pharisees sit in Moses’ seat. 3So you must be careful to do everything they tell you. But do not do what they do, for they do not practice what they preach.
On another occasion in Matthew 22:
23 That same day the Sadducees, who say there is no resurrection, came to him with a question. 24“Teacher,” they said, “Moses told us that if a man dies without having children, his brother must marry the widow and raise up offspring for him. 25Now there were seven brothers among us. The first one married and died, and since he had no children, he left his wife to his brother. 26The same thing happened to the second and third brother, right on down to the seventh. 27Finally, the woman died. 28Now then, at the resurrection, whose wife will she be of the seven, since all of them were married to her?”
Jesus did not hesitate to point out their mistakes:
29 Jesus replied, “You are in error because you do not know the Scriptures or the power of God. 30At the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven. 31But about the resurrection of the dead—have you not read what God said to you, 32‘I am the God of Abraham, the God of Isaac, and the God of Jacob’? He is not the God of the dead but of the living.”
Were the Pharisees misrepresenting Deuteronomy 24:1 concerning divorce?
They might or might not have. In any case, fundamentally, Jesus pointed out the deeper problem was the hardheartedness of the Israelites.
