“Jesus said to them.
And marries another,
καὶ λέγει αὐτοῖς Ὃς ἂν ἀπολύσῃ τὴν γυναῖκα αὐτοῦ καὶ γαμήσῃ ἄλλην, μοιχᾶται ἐπ’ αὐτήν·
This response of Jesus to his disciples can be found also in Matthew, chapter 19:9, where there was also an emphasis on divorce as adultery. Mark indicated that Jesus said to his disciples (καὶ λέγει αὐτοῖς) that whoever divorced his wife (Ὃς ἂν ἀπολύσῃ τὴν γυναῖκα αὐτοῦ) and married another woman (καὶ γαμήσῃ ἄλλην), committed adultery against her (μοιχᾶται ἐπ’ αὐτήν). Jesus had taken the stronger stance of no divorce. However, here there was no exception about sexual misconduct compared to Matthew.
