SEV Biblia, Chapter 46:12
Y los hijos de Judá: Er, y Onán, y Sela, y Fares, y Zara: mas Er y Onán, murieron en la tierra de Canaán. Y los hijos de Fares fueron Hezrón y Hamul.
Clarke's Bible Commentary - Genesis 46:12
Verse 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 on ""ver. 8"": 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.
Matthew Henry Commentary
Verses 5-27 - We have here a particular account of Jacob's family. Though the fulfilling of promises is always sure, yet it is often slow. It was no 215 years since God had promised Abraham to make of him a great nation ch. 12:2; yet that branch of his seed, to which the promise was mad sure, had only increased to seventy, of whom this particular account i kept, to show the power of God in making these seventy become a vas multitude.
