The sons of Judah were Er and Onan. Since the tribe of Judah was so numerous, Moses magnifies the greatness of God's grace by this circumstance, that of the three sons which he begat, two perished in the land of Canaan, by whose loss he might have appeared to be condemned to perpetual sterility. But the climax of God's unparalleled mercy was this, that although two of his children were born of an incestuous connection, they grew up into so great a people.
The sons of Judah [were] Er and Onan: and Er and Onan died in the land of (e) Canaan.
(e) Before Jacob went into Egypt, (Genesis 38:3, Genesis 38:7, Genesis 38:10, Genesis 46:12).
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.
