Matthew 19:3-12
3 And there came to him the Pharisees tempting him, and saying: Is it lawful for a man to put away his wife for every cause?
4 Who answering, said to them: Have ye not read, that he who made man from the beginning, Made them male and female? And he said:
5 For this cause shall a man leave father and mother, and shall cleave to his wife, and they two shall be in one flesh.
6 Therefore now they are not two, but one flesh. What therefore God hath joined together, let no man put asunder.
7 They say to him: Why then did Moses command to give a bill of divorce, and to put away?
8 He saith to them: Because Moses by reason of the hardness of your heart permitted you to put away your wives: but from the beginning it was not so.
9 And I say to you, that whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery: and he that shall marry her that is put away, committeth adultery.
10 His disciples say unto him: If the case of a man with his wife be so, it is not expedient to marry.
11 Who said to them: All men take not this word, but they to whom it is given.
12 For there are eunuchs, who were born so from their mother's womb: and there are eunuchs, who were made so by men: and there are eunuchs, who have made themselves eunuchs for the kingdom of heaven. He that can take, let him take it.
