Er and Onan died in the land of Canaan, and therefore are not contained in the following number, Genesis 46:15. Hezron and Hamul, though they seem to have been born in Egypt, yet are here set down amongst those who came into Egypt, because they came thither in their father's loins, as Levi is said to pay tithes in Abraham, Hebrews 7:9. And the children may as well be said to come thither in their parents, as their father Jacob is said to return from thence, Genesis 46:4, in his children. Object. If this be the sense, why should these two be mentioned rather than the grandchildren of the other brethren, who came into Egypt in the same manner? Answ. This may be done either,
1. From some special excellency or eminency in them above the rest, as Hezron was eminent for being the progenitor of the Messiah, and Hamul might be so for some other cause, though unknown to us. Or,
2. Because they were the first grandchildren that were born in Egypt, and it may be all that were born whilst Jacob lived there, and therefore are not unfitly named with Jacob, and allotted to him; as Joseph's two eldest sons, Ephraim and Manasseh, were by Jacob appropriated to himself, and reckoned as his immediate sons, when all the rest of Joseph's sons were excluded from that privilege, Genesis 48:5,6. And the like may be said of the other two grandchildren mentioned Genesis 46:17.
