2 Samuel 19:20

First—of all the house of Joseph— By the house of Joseph we may very well understand, all the tribes, in opposition to that of Judah, the rights of primogeniture having been divided betwixt Judah and Joseph, 1 Chronicles 5:1. Indeed, when the separation of the two kingdoms of Judah and Israel took place, Benjamin made a part of the former; but before that time, this tribe was rather ranked under that of Joseph, together with those of Ephraim and Manasseh, Psalms 80:2 because it belonged to the same standard. Numbers 2:18. The LXX translate, I am come before any of the house of Joseph; i.e. before any other.
