Genesis 10:20

These are the sons of Ham ,.... His sons and grandsons, which some reckon to be thirty, others thirty one, if the Philistines are taken in:

after their families, after their tongues, in their countries, and in their nations : families of the same language joined together and dwelt in the same country; see Gill on Genesis 10:5 all Africa and a considerable part of Asia were possessed by the four sons of Ham and their posterity; Mizraim had Egypt, and Phut all the rest of Africa; and Cush and Canaan had a large portion in Asia.
