Jo'äh (Heb. Yoäch', יוֹאָח , Jehovah is his brother, i.e. helper), the name of four men.
1. (Sept. Ι᾿ωαά v.r. ῾Ιωάθ,Vulg. Joaha.) The third son of Obed-edom (q.v.), appointed with his brethren to take charge of the sacred furniture (1Ch 26:4). B.C. 1014.
2. (Sept. Ι᾿ωάχ v.r. Ι᾿ωάβ, Ι᾿ωάς, Ι᾿ωαά; but in 2 Chronicles first occurrence Ι᾿ωά v.r. Ι᾿ωδαάδ, second Ι᾿ωαχά; Vulg. Joah.) A Levite of the family of Gershom, the son of Zimmah and father of Iddo (1Ch 6:21); apparently the same elsewhere called ETHAN, and father of Adaiah (ver. 42).
