Of Naamah nothing more is spoken in the Scriptures; but the Targum of Jonathan ben Uzziel makes her the inventress of funeral songs and lamentations. R. S. Jarchi says she was the wife of Noah, and quotes Bereshith Rabba in support of the opinion. Some of the Jewish doctors say her name is recorded in Scripture because she was an upright and chaste woman; but others affirm that the whole world wandered after her, and that of her evil spirits were born into the world. This latter opinion gives some countenance to that of M. De Lavaur.
and the sister of Tubalcain was Naamah; whose name signifies “pleasant”, fair and beautiful; and is thought by some to be the Venus of the Heathens; the Arabic writers (b) say she was a most beautiful woman, and found out colours and painting; and by others Minerva; and Josephus (c) says she excelled in the knowledge of divine things; and Minerva is by the Greeks called Nemanoum (d). The Jews say (e) she was the wife of Noah; and some of them say (f) she was the wife of one Shimron, and the mother of the evil spirit Asmodeus, mentioned in Tobit, and of whom other demons were begotten: the Targuru of Jonathan adds,”she was the mistress of lamentation and songs;”but our Bishop Cumberland (g) conjectures, that she was the wife of Ham, was with him in the ark, and after the flood was the means of leading him into idolatry: what led him to this conjecture was, that he observed in Plutarch, that the wife of Cronus, the same with Ham, is by some called Nemaus, which brought Naamah to his mind. Josephus (h) makes the number of children Lamech had by his two wives to be seventy seven.
The common modern explanation is one of balance: Lamech has two wives: Adah, has two sons mentioned, so Zillah gets two children named also, but one is necessarily a daughter.
