Matthew 19:1-9 (Also found in Mark 10:1-12 and Luke 16:18)
Jesus departed from Galilee, and came into the coasts of Judaea beyond Jordan. Great multitudes followed him; and he healed them there (and he taught them again – Mark 10:1).
Pharisees (tempting Jesus): Is it lawful for a man to put away his wife for every cause?
Jesus: Have ye not read, that he which made them at the beginning made them male and female. For this cause shall a man leave father and mother, and shall cleave to his wife: and they two shall be one flesh? They are no more two, but one flesh. (Genesis 2:24) What God has joined together, let not man put asunder.
Pharisees: Why did Moses then command to give a writing of divorcement, and to put her away?
Jesus: Moses because of the hardness of your hearts suffered you to put away your wives: but from the beginning it was not so. And I say unto you, Whosoever shall put away his wife, except it be for fornication, and shall marry another, commits adultery: and whoso marries her which is put away commits adultery.
And if a woman shall put away her husband, and be married to another, she commits adultery. (Mark 10:12)
Disciples (And in the house – Matthew 10:10): If the case of the man be so with his wife, it is not good to marry.
Jesus: All men cannot receive this saying, save they to whom it is given. For there are some eunuchs, which were so born from their mother’s womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven’s sake. He that is able to receive it, let him receive it.
