1. Son of Enos, and father of Mahalaleel, Genesis 5:9; 1 Chronicles 1:2 .
2. Son of Arphaxad and father of Salah, Luke 3:36 . This Cainan, however, is not named in the three Old Testament genealogies, Genesis 10:24; 11:12; 1 Chronicles 1:24 , nor in any ancient version. The name occurs in two places in the Septuagint, an early Greek version; and some suppose that copyists of Luke's gospel inserted the name, in order to agree with the Septuagint.
