Of anguish. The scene of the sin is also the scene of the punishment.
Commit adultery (μοιχεύοντας)
A wider term than πορνεῦσαι to commit fornication. Compare the metaphorical meaning expressing the rebellion and idolatry of Israel (Jer 3:8; Jer 5:7; Eze 16:32).
With her (μετ' αὐτῆς)
Not with her as the conjux adulteri, but who share with her in her adulteries.
Of their deeds (ἐκ τῶν ἔργων αὐτῶν)
Read αὐτῆς her (deeds). Repent out of (ἐκ) as in Rev 2:21.
