Matthew Henry on Genesis 46:5-27
Old Jacob is here flitting. Little did he think of ever leaving Canaan; he expected, no doubt, to die in his nest, and to leave his seed in actual possession of the promised land: but Providence orders it otherwise. Note, Those that think themselves well settled may yet be unsettled in a little time. Even old people, who think of no other removal than that to the grave (which Jacob had much upon his heart, Gen 37:35; Gen 42:38), sometimes live to see great changes in their family. It is good to be ready, not only for the grave, but for whatever may happen betwixt us and the grave. Observe, 1.

Adam Clarke on Genesis 46:12
The sons of Pharez were Hezron and Hamul - It is not likely that Pharez was more than ten years of age when he came into Egypt, and if so he could not have had children; therefore it is necessary to consider Hezron and Hamul as being born during the seventeen years that Jacob sojourned in Egypt, See Clarke on Gen 46:8 (note): and it appears necessary, for several reasons, to take these seventeen years into the account, as it is very probable that what is called the going down into Egypt includes the seventeen years which Jacob spent there.
John Gill on Genesis 46:12
And the sons of Judah, Er, and Onan, and Shelah, and Pharez,
and Zarah,.... Five of them:
but Er and Onan died in the land of Canaan; and so did not go with Jacob into Egypt; and which is observed that they might not be reckoned among them, though it was proper to take notice of them in the genealogy:
and the sons of Pharez were Hezron and Hamul; some think that these could not be born in Canaan, but in Egypt; and that they are mentioned among those that went down to Egypt, because they went there in the loins of their father, and to supply the places of Er and Onan, who died before, and have the honour to be here named, because they might be the first of Jacob's great grandchildren born…
