Lamech was the the first polygamist mentioned in The Bible. He killed both of his wives.
CAin ANSWER: We do not know who Lamech killed. It seems by the Scripture that Lamech killed someone in self defense but we are not told who in the Bible( Genesis 4:19-24).
It can be found in genesis chapter 4 verse 18.
Which Lamech, the descendent of Cain or the descendant of Seth? If it's the latter, the Bible puts his birth at about 874 years after the expulsion from Eden.
After Cain killed Abel (the first murder in the Bible), he was very afraid that other people would kill him because of what he had done. To protect him, God marked Cain and said that if anyone killed him, that person would be repaid seven times over. The second murder in the Bible was committed by Lamech, a descendant of Cain. Lamech had apparently heard about the mark that was put on his ancestor, and Lamech (not God) told his wives that "if Cain is avenged sevenfold, then Lamech seventy-sevenfold." Thus, the protection given to Cain because of his fear of the consequences of his wickedness inspired Lamech to boast about his own. == ==

Genesis 5:28-31
Yes, according to the Bible at: Genesis 5:28+29Additional information:It should be noted that the Lamech of Genesis 4:18-24 is NOT the same man as the Lamech of Genesis 5:25-29. The first Lamech was a descendent of Cain. The second was a descendent of Seth; the son of Methuselah and father of Noah.
He was the son of Lamech, associated with the origin of metal working (Gen. 4:22).
There were two Lamechs: 1. Lamech in Genesis 4 (also the first polygamist mentioned in the Bible) had two wives: Ada and Tselah. He is known for his "Song of the Sword". 2. Lamech in Genesis 5 was the father of Noah and son of Methuselah. His wife's name is not mentioned in the Bible.
Genesis 5:28 says that Noah's father was Lamech.
Lamech. (There are two different Lamechs; the one descended from Cain rather than Seth is the polygamist.) While the narrative names Lamech's two wives it does not explicitly state that he was the first polygamist... the genealogy in Genesis only names a few people specifically, and simply refers generically to other sons and daughters besides the ones mentioned by name. Lamech is just the first polygamist that's unambiguously pointed out; there may or may not have been others before him.
