Shephuphan.[Shuppîym ,] Shuppim, seems to be merely a contracted form of [Shephûwphâm ,] Shupham, or rather, Shephupham, which, by the mutation of [Mêm,] {mem,} into [Nûwn,] {noon,} is here changed into [Shephûwphân ,] Shephuphan.
Huram.Huram appears to be an error for Hupham in the parallel passage of Numbers, which, by contraction, is written Huppim.
