The names are instead interpreted in the Midrash as an attack on polygamy. "Adah" is there interpreted as "the deposed one", implying that Lamech spurned her in favour of Zillah, whose own name is understood to mean "she shaded herself Zillah at Lamech's side". The Midrash consequently regards Adah as having been treated as a slave, tyrannised by her husband, who was at the beck and call of his mistress, Zillah. It further goes on to claim that part of the immorality, which had led God to flood the earth, was the polygamy practised by Lamech and his generation.
