[If one was] competent and [one was] a deaf-mute, [if] the yavam cohabited with the competent one and then with the deaf-mute, or his brother cohabited with the deaf-mute, he did not disqualify the competent one. [If] the yavam cohabited with the deaf-mute and then with the competent one, or if his brother [then] cohabited with the competent one, he disqualified the deaf-mute.

[If one was] an adult and [one was] a minor, [if] the yavam cohabited with the adult and then with the minor, or [if] his brother [then] cohabited with the minor, he did not disqualify the adult. [If] the yavam cohabited with the minor and then with the adult, or [if] his brother [then] cohabited with the adult, he disqualified the minor. R' Elazar says: We teach the minor to refuse him.
