Adam Clarke Bible Commentary

The flesh of his own arm "The flesh of his neighbor" - "Του βραχιονος του αδελφου αυτου, the Septuagint Alexand. Duplex versio, quarum altera legit רעו reo, quae vox extat, Jer 6:21. Nam רע rea, αδελφος, Gen 43:33. Recte ni fallor." - Secker. I add to this excellent remark, that the Chaldee manifestly reads רעו reo, his neighbor, not זרעו zeroo, his arm; for he renders it by קריביה karibeyh, his neighbor. And Jeremiah has the very same expression: ואיש בשר רעהו יאכלו veish besar reehu yochelu, "and every one shall eat the flesh of his neighbor," Jer 19:9. This observation, I think, gives the true reading and sense of this place: and the context strongly confirms it by explaining the general idea by particular instances, in the following verse: "Every man shall devour the flesh of his neighbor;" that is, they shall harass and destroy one another. "Manasseh shall destroy Ephraim, and Ephraim, Manasseh;" which two tribes were most closely connected both in blood and situation as brothers and neighbors; "and both of them in the midst of their own dissensions shall agree in preying upon Judah." The common reading, "shall devour the flesh of his own arm," in connection with what follows, seems to make either an inconsistency, or an anticlimax; whereas by this correction the following verse becomes an elegant illustration of the foregoing. - L.
