New Defender's Study Bible Notes
3:2 families of the earth. The expression “all the families of the earth” indicates that God’s dealings are with families or tribes, not races. Neither the term nor concept of “race” is found in Scripture. The original division was by “the families of the sons of Noah” (Genesis 10:32), evidently as enumerated in the Table of Nations (Genesis 10). These were also distinguished by their “tongues,” after the confusion of tongues at Babel (note Genesis 10:5,20,31).
