Dedan - See Ezekiel 27:15. It is remarkable that "Dedan and Sheba" occur both among the descendants of Ham in Genesis 10:7, and among the descendants of Abraham and Keturah in Genesis 25:3. This seems to indicate that there were distinct nomad tribes bearing the same names of Hamite and of Semitic origin; or it may be that whereas some of the nomad Arabs were Hamite, others Semitic, these were of mixed origin, and so traced up their lineage alike to tiara and Shem. Here we have, at any rate, a number of Arabian nomad tribes mentioned together, and these tribes and their caravans were in those days the regular merchant travelers between east and west. By her ships, Tyre spread over Europe the goods which by these caravans she obtained from India and China.
Precious clothes - Or "clothes of covering," cloths of tapestry.

Dedan - Possibly the descendants of Dedan, son of Raamah, see Genesis 10:7.
In precious clothes for chariots - Either fine carpets, or rich housings for horses, camels, etc., used for riding.

Dedan was thy merchant in precious cloths for chariots. Or, "cloths of freedom" (u); such as freemen and even nobles wore; and yet so extravagant were the Tyrians, that they bought these to line or cover their chariots with; this is different from the Dedan in Ezekiel 27:15, and is either Dedan in Edom or Idumea, Jeremiah 49:8, or in Arabia, the inhabitants of which descended from Dedan, a grandson of Abraham, Genesis 25:3, which agrees with the following.
