Frequently Asked Questions
Q: What does Deuteronomy 3:18 mean?
A: Deuteronomy 3:18 recounts Moshe's (Moses') instruction to the tribes of Reuven, Gad, and half of Menashe. Although they had already received their inheritance on the eastern side of the Jordan River, they were commanded to join the other tribes in conquering the land of Canaan (Eretz Yisrael) before settling their own portion. This teaches the importance of unity and mutual responsibility among the Jewish people.
Q: Why was it important for these tribes to help conquer Canaan?
A: According to Rashi and other commentaries, the tribes of Reuven, Gad, and half of Menashe had a moral obligation to assist their brethren in conquering the land, even though they had already received their portion. This teaches the principle of 'kol Yisrael areivim zeh lazeh'—all Jews are responsible for one another (Talmud Shevuos 39a). Their participation ensured unity and collective fulfillment of Hashem's promise.
Q: What can we learn from Deuteronomy 3:18 today?
A: This verse teaches the importance of helping others achieve their goals before focusing solely on our own needs. Just as these tribes were required to assist in conquering the land before settling theirs, we too must prioritize communal responsibility (Rambam, Hilchos De'os 6:3). It also emphasizes the value of unity among the Jewish people in fulfilling our shared mission.
Q: Why does the verse specify 'all that are fit for the war'?
A: The phrase 'all that are fit for the war' (כָּל־בְּנֵי־חָיִל) teaches that only able-bodied men were required to fight, excluding those with legitimate exemptions (such as those who had just built a home, planted a vineyard, or were newly married—see Deuteronomy 20:5-8). This shows Hashem's compassion, as He does not demand unnecessary hardship (Rashi on Deuteronomy 3:18).
Q: How does this verse connect to the broader theme of Sefer Devarim (Deuteronomy)?
A: Deuteronomy 3:18 reflects Sefer Devarim's emphasis on unity, responsibility, and preparing the nation to enter Eretz Yisrael. Moshe reminds the people of past events to reinforce commitment to Torah and mitzvos in the land. The Ramban explains that this repetition ensures the lessons are passed to future generations, highlighting the eternal bond between the Jewish people and Eretz Yisrael.
Context in Sefer Devarim
This verse (Devarim 3:18) appears in Moshe Rabbeinu's recounting of the events after the conquest of the lands of Sichon and Og. The tribes of Reuven, Gad, and half of Menashe requested these lands for their inheritance, and Moshe agreed on the condition that their warriors would first assist the other tribes in conquering Eretz Canaan.
Rashi's Explanation
Rashi explains that the phrase "חֲלוּצִים תַּעַבְרוּ" (pass over armed) refers to the obligation of the eastern tribes to lead the battlefront. The term "חֲלוּצִים" implies being prepared for war, as in Shemot 13:18 where Bnei Yisrael left Egypt "חֲמֻשִׁים" (armed). Rashi emphasizes that this was a binding condition for their inheritance east of the Jordan.
Rambam's Perspective
In Hilchot Melachim (6:1), Rambam derives from this verse that all of Israel must participate in obligatory wars (milchemet mitzvah), including the conquest of Eretz Yisrael. The eastern tribes' commitment to fight alongside their brethren establishes a principle of collective responsibility in national mitzvot.
Talmudic Insights
Nachmanides' Additional Commentary
Ramban notes that the eastern tribes' willingness to separate temporarily from their families to fulfill this mitzvah showed extraordinary dedication. He connects this to the broader theme in Sefer Devarim of maintaining unity and mutual responsibility among Klal Yisrael.
Halachic Implications
The Sifrei derives from this verse that the mitzvah of settling Eretz Yisrael applies to all generations, not just the initial conquest. The eastern tribes' obligation to assist in conquering the land - despite having already received their portion - teaches that all Jews share responsibility for the land's settlement and protection.
