International Standard Bible Encyclopedia (1915)
shed’-e-ur, she-de’-ur (shedhe’ur, "daybreak"; Codex Vaticanus Sediour, Ediour): The father of Elizur, the chief of Reuben (Nu 1:5; 2:10; 7:30). French Delitzsch correctly conceives the name as an Assyrian compound, sad uri, "daybreak." Cf, however, Gray, HPN, 169, 197, who emends the text to read Shaddai ’Ur, "Shaddai is flame."
