1 Chronicles 5:1

The son of Israel This is added emphatically, because the sons of Joseph, Manasseh, and Ephraim were treated as if they had been the immediate sons of Jacob. The genealogy is not to be reckoned after the birthright This is the second reason which showeth both why Reuben's genealogy was not first mentioned, and if another tribe was to be ranked before it, why that was Judah, and not Joseph, because the order of their genealogy was not to be ruled by the birthright, but by a higher privilege, which was given to Judah.
