Gera: Jdg 3:15
Shephuphan: שׁפם [Strong's H8206], Shuppim, seems to be merely a contracted form of שׁפופם [Strong's H8197], Shupham, or rather, Shephupham, which, by the mutation of מ, mem, into נ, noon, is here changed into שׁפופן [Strong's H8197], Shephuphan. 1Ch 7:12, Shuppim, Num 26:39, Shupham
Huram: Huram appears to be an error for Hupham in the parallel passage of Numbers, which, by contraction, is written Huppim.
