Genesis 25:3

25:3 Jokshan became the father of Sheba and Dedan. 11  The descendants of Dedan were the Asshurites, Letushites, and Leummites.

sn The descendants of Seba settled in Upper Egypt along the Nile.

sn The Hebrew name Havilah apparently means “stretch of sand” (see HALOT 297 s.v. חֲוִילָה). Havilah’s descendants settled in eastern Arabia.

sn The descendants of Sabtah settled near the western shore of the Persian Gulf in ancient Hadhramaut.

sn The descendants of Raamah settled in southwest Arabia.

sn The descendants of Sabteca settled in Samudake, east toward the Persian Gulf.

sn Sheba became the name of a kingdom in southwest Arabia.

sn The name Dedan is associated with àUla in northern Arabia.

sn Obal was a name used for several localities in Yemen.

sn The name Abimael is a genuine Sabean form which means “my father, truly, he is God.”

10 sn The descendants of Sheba lived in South Arabia, where the Joktanites were more powerful than the Hamites.

11 sn The names Sheba and Dedan appear in Gen 10:7 as descendants of Ham through Cush and Raamah. Since these two names are usually interpreted to be place names, one plausible suggestion is that some of Abraham’s descendants lived in those regions and took names linked with it.
