First Chronicles 2:42 identifies this Mesha as a son of Caleb in Judah's genealogy. The name shares the same form and likely meaning ('deliverance') as other biblical Meshas, though this is a distinct individual. The Greek and Syriac versions show textual variation (Mareisa, Musa), suggesting some manuscript uncertainty. He appears in the detailed genealogical records that trace the descendants of Judah, particularly the Calebite clans that held territory in southern Judah around Hebron.
