Numbers 26:19-22

And the sons of Judah were Er and Onan ,.... And besides these he had Shelah, Pharez, and Zerah, from whom families sprang, but none from the two first: for

Er and Onan died in the land of Canaan ; where they were born; and that because of their sins, as the Targum of Jonathan adds, see

Ge 38:7-10 so that there were but three families sprang from Judah, the Shelanites, Pharzites, and Zarhites; only the family of the Pharzites was divided into two families, the Hesronites and the Hamulites, so called from two sons of Pharez; the number of these families amounted to 76,500, so that there was an increase of 1900 since the last muster, which answers to Jacob's blessing, that he should be a praise among his brethren, Genesis 49:8 .
