Numbers 26:19
The sons of Judah were Er and Onan: and Er and Onan died in the land of Canaan.
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 Genesis 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.
