Lamech (/ˈleɪmɪk/;Hebrew: לֶמֶךְ Lemeḵ) is a person in Cain's genealogy in the 4th chapter of the Book of Genesis. He is the sixth generation descendant of Cain (Genesis 4:18); his father was named Methusael, and he was responsible for the "Song of the Sword". He is also noted as the first polygamist mentioned in the Bible, taking two wives, Adah and Zillah (Tselah).
Sandwiched between two genealogical lines, the passage describing Lamech, son of Methushael, descendant of Cain and his children is fairly substantive:
There are various suggestions of the correct translations for the names:
When fully translated, the text has a strong resemblance simply to a basic mythology concerning the origin of the various forms of civilisation, the shepherds and musicians being products of the day, and pleasure being a product of the night. Blacksmiths, in carrying out their trade, are also associated with the darkness. Thus, in a sense, Lamech could be interpreted as a culture hero. Some of the names also appear to demonstrate punning - Jabal, Jubal, and Tubal rhyme, and appear to be derived from the same root - JBL (YVL in modern Hebrew): to bring forth, (also) to carry. A similar description existed amongst Phoenicians.
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 [from 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.
