דברים, פרק ל״ג, פסוק ו׳

As Moses prepares to impart his final blessings to the tribes of Israel just before his death, he opens with a brief, highly focused blessing for the tribe of Reuben. Centered on the fundamental values of existence, survival, and continuity, this opening reflects the tribe's complex history and its unique position on the eve of entering the Promised Land. Reuben is addressed first because he is the firstborn, making it fitting for him to receive the primary blessing. Furthermore, this tribe was the first to receive its territorial inheritance across the Jordan River and the first to march as the vanguard ahead of the camp during the conquest of the land [רמב״ן, אבן עזרא, אברבנאל].

Notably absent from this sequence of blessings is Reuben's brother, Simeon. The primary approach among commentators attributes this omission to the tribe's grave sin at Baal Peor, where the Simeonites were the central transgressors and their leader was slain [רש״י, אבן עזרא, הטור הארוך]. Conversely, another perspective suggests that Simeon's exclusion stems from a numerical constraint. The Torah consistently maintains a count of exactly twelve tribes. Because God commanded that Joseph be divided into two distinct tribes, Ephraim and Manasseh, and because Moses was obligated to bless the tribe of Levi, through whom all of Israel is blessed, one tribe had to be omitted to preserve the typological number of twelve. Simeon was chosen for this omission because the tribe was relatively small, its territory was entirely encompassed within the borders of Judah, and it was destined to be included within Judah's blessing [רמב״ן, שד״ל, אברבנאל].

The blessing bestowed upon Reuben operates on two primary levels, addressing both the physical and the spiritual. On a physical and military level, the blessing speaks directly to the tribe's geographic vulnerability and martial responsibilities. The Reubenites chose to settle across the Jordan River in an area exposed to enemy attacks, and they committed to crossing into the Promised Land as the vanguard to fight on behalf of the rest of the nation. Moses prays that they will live securely in their territory and that these warriors, who are marching at the very front of the camp into the most dangerous positions, will succeed in their battles and not lose their lives [ספורנו, אברבנאל, בכור שור, העמק דבר].

On a spiritual and historical level, the blessing serves as a prayer for atonement, ensuring that the tribe's past transgressions do not compromise its future. Moses asks that Reuben live in this world and not die in the World to Come, meaning the tribe will not forfeit its eternal spiritual portion due to Reuben's ancient sin concerning his father's concubine, Bilhah [רש״י, תרגום אונקלוס, רבנו בחיי, שפתי כהן]. Other commentators view this as a prayer for the tribe's ongoing survival following the disastrous involvement of prominent Reubenites, Dathan and Abiram, in Korah's rebellion. Since many of their leaders perished in that uprising, Moses prays that the entire tribe will not be eradicated for that sin [אור החיים, צרור המור].

The conclusion of the blessing focuses specifically on the men of the tribe, referring to distinguished individuals and heroes fit for war [העמק דבר, כלי יקר, מלבי״ם]. There are three main interpretations of this final promise. Continuing the military theme, one approach suggests that Moses is blessing the warriors heading into battle, praying that they will return home in the exact same numbers, without a single soldier missing from their ranks [רא״ש, פני דוד, הדר זקנים, בכור שור]. A second approach understands this as a promise of enduring continuity and status, with Moses praying that the tribe of Reuben will always be counted among the tribes of Israel and never be removed from the tally of the twelve despite its historical missteps [רש״י, רמב״ן]. A third perspective offers a different reading, suggesting that the negation from the previous phrase carries over into the end of the blessing. In this view, Moses is praying that their numbers should not be countable. He blesses the tribe to multiply so vastly that its people become innumerable, as anything that can be easily counted is ultimately considered small [אבן עזרא, רבנו בחיי, אברבנאל].
