Jubal is a biblical figure in Genesis 4:21 of the Hebrew Bible and Old Testament. Mentioned only once, he is sometimes regarded by Christians, particularly by medieval commentators, as the 'inventor of music'. A descendant of Cain, his father is Lamech and his brother is Jabal.

Cain is a biblical figure in the Book of Genesis within Abrahamic religions. He is the elder brother of Abel, and the firstborn son of Adam and Eve, the first couple within the Bible. He was a farmer who gave an offering of his crops to God. However, God was not pleased and favored Abel's offering over Cain's. Out of jealousy, Cain killed his brother, for which he was punished by God with the curse and mark of Cain. He had several children, starting with Enoch and including Lamech.
