The disciples said to him, "If this is the situation between a husband and wife, it is better not to marry."
Jesus replied, "Not everyone can accept this word, but only those to whom it has been given.1
References for Matthew 19:11
For some are eunuchs because they were born that way; others were made that way by men; and others have renounced marriage because of the kingdom of heaven. The one who can accept this should accept it."
