Boyd’s Bible Dictionary:
(division). Son of Eber. His family remained in Mesopotamia (Gen. 10:25; 11:16-19).
Concise Bible Dictionary:
Son of Eber, a descendant of Shem. The name signifies “division,” and apparently he was so called because “in his days was the earth divided” (Gen. 10:25). This doubtless means, as is said in Genesis 10:5, “By these were the isles of the Gentiles divided in their lands”; and again in Genesis 10:32, “By these were the nations divided in the earth after the flood.” In the next chapter is the account of the confusion of tongues and the scattering of the people generally (Gen. 11:16-19; 1 Chron. 1:19, 25).
