The torn garments; the torn tribe[1]
ויתן להם משה לבני-גד ולבני ראובן ולחצי שבט מנשה בן-יוסף את-ממלכת סיחן מלך האמרי ואת-ממלכת עוג מלך הבשן וגו’
Moshe gave to the tribe of Gad, the tribe of Reuven, and half of the tribe of Menashe, the son of Yosef, the kingdom of Sichon, the king of the Emorites, and the kingdom of Og, king of the Bashan…[2]
The Torah describes an interesting interaction between the tribes of Reuven and Gad[3]. They had abundant flock, and noticed that the recently conquered land on the East side of the Jordan river was suitable for flock. They requested to Moshe that they stay on that side of the river, and not join their brothers into the Land of Israel proper, on the west side of the Jordan. After a whole back and forth, Moshe eventually agreed to their request. Seemingly out of nowhere, Moshe also decided to allocate some of this land for half of the tribe of Menashe. They seemingly didn’t request this, so why did Moshe do this[4]? Also, why only half the tribe, and not the whole tribe?
