| Gill's Exposition of the Entire Bible 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.
Keil and Delitzsch Biblical Commentary on the Old TestamentThe sons and families of Judah agree with Genesis 46:12 (cf. Genesis 38:6.); also with 1 Chronicles 2:3-5.
Geneva Study BibleThe sons of Judah were Er and Onan: and Er and Onan died in the land of {e} Canaan. (e) Before Jacob went into Egypt, Ge 38:3,7,10,46:12.
Matthew Henry's Concise Commentary26:1-51 Moses did not number the people but when God commanded him. We have here the families registered, as well as the tribes. The total was nearly the same as when numbered at mount Sinai. Notice is here taken of the children of Korah; they died not, as the children of Dathan and Abiram; they seem not to have joined even their own father in rebellion. If we partake not of the sins of sinners, we shall not partake of their plagues. |
