Paul speaks of his care for the Corinthian believers as if he had promised another man that he would prepare his daughter to marry him and he is most concerned that he be able to keep his promise to the man. Alternate translation: "I was like a father who promised to present his daughter to one husband. I promised to keep you as a pure virgin so I could give you to Christ" (See: [[rc://en/ta/man/translate/figs-metaphor]])
