A passage from the 13th-century anonymous Georgian "Histories and Eulogies of Sovereigns" relates that David was under the patronage of Tamar's paternal aunt Rusudan and came of "the descendants literally, "sons" of Ephraïm, which are Osi, handsome and strong in battle." The Georgian scholar Korneli Kekelidze suggested that David Soslan's family – the "Ephraïmids" – might have claimed descent from the biblical Ephraim, and compared this family legend to that of the Bagratids who considered themselves descendants of David, the second king of the Israelites.
