(Devarim, Ibid.) "And his men will be counted": "heroic" in strength; "heroic" in Torah. "heroic in strength": viz. (Isaiah 3:25): "Your men will fall by the sword, and your strong ones in the war." "heroic" in Torah: viz. (Psalms 103:20) "heroic" in strength, doing His word (Torah)." And (I Chronicles 5:6) "Be'erah was his son, who was exiled by Tiglath-Pilneser, king of Asher. He was the leader of the Reuvenites." Thus, Reuven shall live and he shall not die."
(Devarim 33:7) "And this ("heroism" of Reuven [ in confessing his sin]) was due to Judah, who confessed (his sin [viz. Bereshith 38:26]). Of them Scripture writes (Iyyov 15:18-19) "Wise men have told (their sin); they did not conceal it from their fathers. To them alone the land was given; no stranger passed among them."
