Beth-el was not taken by Joshua, though he took Ai, which was nigh to it. Instead of יוסף בית beith Yoseph, "the house of Joseph," ten of Dr. Kennicott's MSS. and six of De Rossi's have יוסף בני beney Yoseph, "the children of Joseph;" and this is the reading of both the Septuagint and Arabic, as well as of two copies in the Hexapla of Origen.
Bethel was within the borders of Benjamin, but was captured, as we here learn, by the house of Joseph, who probably retained it.
