Zerah

This Zerah was a Levite of the Gershonite clan, the son of Iddo and father of Jeatherai, listed in the genealogy of the Levitical musicians in 1 Chronicles 6:21. He belongs to the ancestral line of Asaph, one of David's three chief musicians. Several other men named Zerah appear in the biblical record, most prominently Zerah the twin son of Judah and Tamar (Genesis 38:30) and Zerah the Cushite who invaded Judah during Asa's reign (2 Chronicles 14:9).
