V'zot haBracha: Reuven's Blessing

(30) Jacob said to Simeon and Levi, “You have brought trouble on me, making me odious among the inhabitants of the land, the Canaanites and the Perizzites; my fighters are few in number, so that if they unite against me and attack me, I and my house will be destroyed.”

(4) IN THAT HIS MEN BECOME FEW. is to be rendered, "and let his men not be numbered (few)." It is similar to "And I have not learned wisdom (Prov. 30:3)" and to the bet of "be-el shaddai" as I have explained many times. Moses said this because it is possible for the tribe of Reuben to live forever but consist of few people. All things that are numbered are few. Compare, "And I am men of number (Gen. 34:30)."

(20) Moses said to them, “If you do this, if you go to battle as shock-troops, at the instance of יהוה, (21) and every shock-fighter among you crosses the Jordan, at the instance of יהוה, until [God] has personally dispossessed the enemies, (22) and the land has been subdued, at the instance of יהוה, and then you return—you shall be clear before יהוה and before Israel; and this land shall be your holding under יהוה. (23) But if you do not do so, you will have sinned against יהוה; and know that your sin will overtake you. (24) Build towns for your children and sheepfolds for your flocks, but do what you have promised.” (25) The Gadites and the Reubenites answered Moses, “Your servants will do as my lord commands. (26) Our children, our wives, our flocks, and all our other livestock will stay behind in the towns of Gilead; (27) while your servants, all those recruited for war, cross over, at the instance of יהוה, to engage in battle—as my lord orders.”

(1) (Devarim 33:6) "Reuven shall live and he shall not die": How is this related to what precedes [("together, the tribes of Israel")]? This is analogous to (the situation of) a king, who visits his sons on occasion. When he takes leave of them, they and his kinsmen come to escort him. He says to them: "My sons, is there anything that you need? Is there anything on your mind?" They answer: "Father, there is nothing that we need and nothing that we desire of you but that you forgive our big brother." If not for the tribes' (intercession), the L-rd would not have forgiven Reuven (for the episode of Bilhah [viz. Bereshith 35:22]) — wherefore it is written (at this point) "together, the tribes of Israel."

(2) (Devarim, Ibid.) "Reuven shall live and he shall not die." — But did he not die? What, then, is the intent of "he shall not die"? In the world to come.

(3) Variantly: "Reuven shall live for his act with Joseph (viz. Bereshith 37:21), and he shall (therefore,) not die for his act with Bilhah. R. Chanina b. Gamliel says: Merit is not exchanged for liability, nor liability for merit — except for the instance of Reuven (above) and that of David (viz. II Samuel 16:13) … And the sages say: Neither merit for liability nor liability for merit, but mitzvoth are rewarded and transgressions are punished. And what is the import of "Reuven shall live and he shall not die"? That he repented of his deed. R. Shimon b. Gamliel says: Reuven was far removed from that sin (of cohabitation with Bilhah) and he did not descend to that act. Is it possible that he would stand at the head of the tribes on Mount Eival and say (Devarim 27:20) "Cursed be he who lives with father's wife," having descended to such an act! What, then, is the intent of (Bereshith 49:4) "For you went up on your father's bed?" He was solicitous of his mother's honor (viz. Shabbath 55b).

It is more correct to explain: “Let Reuben live in Israel; and not die, that his tribe at no time should be cut off, and that his numbers always be among the count of the children of Israel.” He prayed for him that his name not be cut off from Israel because of the anger with which his father was wroth with him when he defiled his couch. This is similar to what is stated there, "and Reuben went and lay with Bilhah his father’s concubine; and Israel heard of it. Now the sons of Jacob were twelve." Scripture made it be known that he was not excluded from that number on account of his sin. Rashi also explained it this way. And the meaning of his men [and let ‘his men’ be numbered among the men of Israel] is that all his men should deserve this [to be included in the ranks of Israel], and not even part of their tribe be cut off because of his [Reuben’s] sin. Perhaps the expression his men refers to the heads of the four families [of the tribe of Reuben — Hanoch, Pallu, Hezron, and Carmi], and the meaning of the word mispar (number) is like b’mispar [with the prefix beth meaning “in the number,” the verse stating: “and let his men be ‘in’ the number” of the children of Israel]. Similarly, to play the harlot ‘beith’ [literally: “the house of”] her father [means b’veith — “in the house of” her father]; they shall wash ‘mayim’ [literally: “water,” means b’mayim — “with water”]. There are many similar cases.

Or it may be that the meaning thereof is that in the census of Israel his men be counted first as is the right of the firstborn, for number one is the unit from which all numbers originate.
Onkelos rendered it: “And his children will receive their inheritance among their numbers.” He meant what we have explained, saying that Reuben will live and not be cut off [from Israel] and his men will be counted among their numbers forever. His tribe will not be blotted out from Israel but they will not be counted on account of their large numbers as forming two tribes. Thus he deprived him of the birthright [that awards the firstborn with a double share], but he assured him of being forever one tribe.
