John Wesley on 2 Samuel 19:20

House of Joseph - The house of Joseph is here put for all the tribes, except Judah, which are fitly distinguished from Judah, because the rights of the first - born were divided between Judah and Joseph, 1Chron 5:2. And though Benjamin, after the division of the kingdoms was fitly joined with Judah, because then they adhered to that tribe; yet before that time it was joined with Joseph, because they marched under the standard of the house of Joseph, or of Ephraim, Numb 10:22,23,24. Whence it is, that Ephraim, Benjamin, and Manasseh, are put together, Psal 80:2.
