Joshua’s closing charge and assurance

These verses sit inside the allotment narratives, where tribal territories are assigned and disputes or limitations surface (Joshua 13–21). Immediately before this, Ephraim and Manasseh complain about having only one “lot” and about the hill country being wooded and the valleys being occupied by Canaanites with iron chariots (17:14–16). Joshua’s response (17:17–18) both corrects their expectations and reframes the problem: their inheritance is not only what is already cleared and uncontested, but what they will actively take and develop. The passage functions as a short, direct ruling that combines encouragement and instruction.

The scene assumes early Israelite settlement in Canaan, with multiple local peoples still living in the land and controlling key areas, especially open valleys suitable for chariots. “House of Joseph” refers to the related tribes of Ephraim and Manasseh, who together form a large population group expecting an adequate share. Hill country settlement often required clearing trees, building terraces, and expanding village networks, while lowland areas could be harder to penetrate militarily because chariots were effective on flatter ground. The text portrays a practical, incremental process: settle, clear, expand boundaries, and displace remaining city-state populations over time.

Shared ground

Joshua answers a land complaint from the “house of Joseph” (Ephraim and Manasseh together). He agrees with their basic premise that they are large and capable: they are “a great people” with “great power.” That affirmation is paired with a correction: their inheritance is not meant to stay at the level of a single, already-secured portion.

Joshua then lays out one integrated plan: the hill country is truly theirs, but it is not yet fully usable or fully controlled. It will require development (clearing forest) and continued expansion (“the outer edges” becoming theirs). He also addresses their stated fear of the valley forces—Canaanites with iron chariots—by assuring that these opponents can be driven out despite their strength.

Where interpretation differs

Some readers take “you shall drive out the Canaanites” mainly as a promise of outcome—Joshua predicting success based on God’s prior commitments and the tribes’ capacity. Others read it mainly as a directive—Joshua insisting they must act decisively, with the statement functioning like a firm charge. In either case, the verse connects assurance with responsibility: strength and divine backing are not presented as reasons for passivity.

A second, smaller difference concerns “one lot.” Some understand it as “one contiguous territory,” meaning Joseph’s tribes want a broader region. Others hear it as “one initial allotment,” with Joshua saying they are not limited to what is already measured out but may enlarge their holding by taking and developing more.

Why the disagreement exists The passage uses short, forceful future-tense statements that can sound like either prediction (“you will…”) or directive (“you shall…”). Also, phrases like “one lot” and “the goings out of it” are compact land-language that can be heard more than one way without changing the overall thrust.

What this passage clearly contributes It presents inheritance as both granted and to-be-realized: Joshua assigns the hill country as theirs (explicit), yet he also frames the full enjoyment of it as requiring clearing, settling, and pushing outward (explicit). It also treats military threats realistically—iron chariots and strong opponents are acknowledged (explicit)—while insisting they are not decisive barriers to possession (explicit assurance).
