Matthew 19:10

They asked him, “Why then did Moses command us to give her a certificate of divorce and divorce her?”

He said to them, “Moses, because of the hardness of your hearts, allowed you to divorce your wives, but from the beginning it has not been so.

I tell you that whoever divorces his wife, except for sexual immorality, and marries another, commits adultery; and he who marries her when she is divorced commits adultery.”

But he said to them, “Not all men can receive this saying, but those to whom it is given.

For there are eunuchs who were born that way from their mother’s womb, and there are eunuchs who were made eunuchs by men; and there are eunuchs who made themselves eunuchs for the Kingdom of Heaven’s sake. He who is able to receive it, let him receive it.”

Then little children were brought to him that he should lay his hands on them and pray; and the disciples rebuked them.
