Nowell, “Book of Tobit,” pp. 108–109, n. 5. Tobit and Tobias derive from the Hebrew for “the Lord is my good”; Raguel is from “friend of God” (the name is shared with Moses’ father-in-law [Exodus 2:18; Numbers, 10:29] and is the name of an archangel in 1 Enoch 20:4, cf. 23:4); Raphael is from “God heals”; and Azariah is from “God has helped.”
