🔼The name Aran in the Bible
The only Aran in the Bible is a son of Dishan and brother of Uz (Genesis 36:28), and Dishan is the seventh son of Seir the Horite (and not, as pretty much all the sources maintain, of Esau; see Genesis 36:20).
🔼Etymology of the name Aran
The name Aran comes from the curious root group ארן ('rn I & II):
For a meaning of the name Aran, Jones' Dictionary of Old Testament Proper Names, NOBSE Study Bible Name List and BDB Theological Dictionary all go with the Syriac word that denotes a kind of wild goat and read Wild Goat.
But Alfred Jones (Dictionary of Old Testament Proper Names) additionally mentions a Hebrew onomasticon (perhaps that of Hillerus, or even older) that traditionally translates the name Aran with An Ark (see the name Aaron).
