Mahalalel is an Antediluvian patriarch named in the Hebrew Bible. He is mentioned in the Sethite genealogy as the grandfather of Enoch and subsequently the ancestor of Noah.
Mahalalel as depicted in the Nuremberg Chronicle (1493 CE).
The patriarchs of the Bible, when narrowly defined, are Abraham, his son Isaac, and Isaac's son Jacob, also named Israel, the ancestor of the Israelites. These three figures are referred to collectively as "the patriarchs", and the period in which they lived is known as the patriarchal age.
