Shelah (son of Judah)

According to the Bible, Shelah/Shela was the third son of Judah, and was born at Chezib, which can be identified with an unknown town in the vicinity of Mareshah.

Biblical narrative
According to the book of Genesis, God had killed Shelah's two older brothers, Er and Onan. Judah was unwilling to allow Tamar, who had been successively Er's and Onan's wife, to be married to Shelah. Judah's concern was that Tamar might be cursed and Shelah might die if married to her. So Judah told her to wait until Shelah had grown up. When Shelah came of age, Judah neglected to marry him to Tamar. In the Book of Chronicles, Shelah is identified as the name of a clan, containing a subclan named Er.

According, the sons of Shelah were: The descendants of the last 4 sons were potters who dwelt at Netaim and Gederah and worked for the king.
 * Er, the father of Lecah
 * 1) Laadah, the father of Mareshah.
 * 2) The families of the house of the linen workers of the house of Ashbea
 * 3) Jokim, the men of Chozeba
 * 4) Joash
 * 5) Saraph
 * 6) Jashubi-Lehem

According to some biblical scholars, the description of Shelah is an eponymous aetiological myth concerning fluctuations in the constituency of the tribe of Judah, with Shelah representing the newest clan to become part of the tribe. The Book of Chronicles' description of Er as a descendant of Shelah, suggests that Er was in reality the name of a clan that was originally equal in status to the Shelah clan, but was later subsumed by it.

Professor Aaron Demsky argues that the genealogy of Shelah is an allegory of the history of Shelanite clans in Shephelah (i.e. Judean foothills). Remnants of the Er clan joined the Shelanites and founded the city of Lecah, which was the alternative name for Lachish. Later, the Laadah clan founded Mareshah, a town of secondary importance to Lachish. The families of Beth Asheba lived in a town of the same name and produced clothing for the priesthood and aristocracy, using byssus cloth. The Jokim clan founded Chozeba, which was synonymous with the Chezib near Mareshah. The Joash and Saraph clans lived with the Moabites. The last Shelanite clans to emerge consisted of the residents of Lahem or Lahmas. The last four clans worked for the king, who was most likely Hezekiah.

In 701 BC, Sennacherib destroyed important Shelanite cities. Survivors fled to Jerusalem and assimilated with the local populace after the return of Babylonian exiles in c.a. 538 BC. According to Demsky, the author of the Book of Chronicles considered the Shelanite clans to be inferior to other Judahite clans, based on their positioning in the biblical text.

Scholars have argued that the Tamar and Shelah narrative has a secondary role in either promoting the institution of levirate marriage, or presenting an aetiological myth for its origin; Shelah's role in the narrative would thus be as the example of a brother refusing to perform levirate marriage. John Emerton regards the evidence for this as inconclusive, though classical rabbinical writers argued that this narrative concerns the origin of levirate marriage.
