Matthew 19:

10 The disciples said to Jesus, “If the relationship of the man with his wife is like this, it is better not to marry.” 11 But He said to them, “Not all men can accept this statement, but only those to whom it has been given. 12 For there are eunuchs who were born that way from their mother’s womb; and there are eunuchs who were made eunuchs by people; and there are also eunuchs who made themselves eunuchs for the sake of the kingdom of heaven. The one who is able to accept this, let him accept it.”

1 Corinthians 7:

1 Now concerning the things about which you wrote, it is good for a man not to touch a woman. [2-5 INTERPOLATION] 6 But this I say by way of concession, not of command. 7 Yet I wish that all men were even as I myself am. However, each has his own gift from God, one in this way, and another in that...28 But if you marry, you have not sinned; Yet such people as yourselves will have trouble in this life, and I am trying to spare you...32 One who is unmarried is concerned about the things of the Lord, how he may please the Lord; 33 but one who is married is concerned about the things of the world, how he may please his wife, 34 he is divided. The woman who is unmarried is concerned about the things of the Lord, that she may be holy both in body and spirit; but one who is married is concerned about [the things of the world,] how she may please her husband. 35 I say this for your own benefit, not to put a restraint on you, but to promote what is appropriate and to secure undistracted devotion to the Lord.
