Shared ground

Joshua 3:5–6 presents Israel on the verge of a major transition. Joshua gives two linked directions: the people are to “sanctify” themselves, and the priests are to take up the ark of the covenant and move ahead of everyone else. The text ties the people’s preparation to a near-term expectation: “tomorrow” Yahweh will do “wonders” among them. Then it highlights prompt priestly compliance: they lift the ark and go in front.

A clear theme is ordered movement under Yahweh’s direction. The ark’s leading position signals that the crossing will not be driven merely by human strategy; it is framed as Yahweh acting, with Israel arranged around his presence and covenant.

Where interpretation differs (only where needed)

Two main questions draw different readings.

First, what “sanctify yourselves” involved in that moment. Some read it as mainly ritual preparation (washing, abstaining from normal activities, being in a state fit for a sacred event). Others think it includes moral readiness as well (turning from sin, repairing breaches), even if the specific actions are not spelled out here.

Second, how to take the timing (“tomorrow”) and the sequence in v. 6. Some read v. 6 as happening right after the speech (same day), as part of immediate preparations. Others think v. 6 reports the next day’s action in advance, so the narrative is briefly anticipating the next scene (compare Joshua 3:7).

Why the disagreement exists The passage gives commands and an outcome (“wonders”) but does not list the concrete steps of sanctifying, so readers infer from other Israelite preparation scenes. Also, Hebrew narrative can report events with tight sequencing even when the writer is summarizing or previewing what will happen next, which affects whether v. 6 is read as “now” or “tomorrow.”

What this passage clearly contributes Explicitly, the text says (1) Joshua calls for consecration, (2) Yahweh will do wonders “tomorrow,” (3) the priests must lift and carry the ark of the covenant, (4) the ark is to go ahead of the people, and (5) the priests obey and take the lead. Theologically (as an inference from these claims), the passage presents Yahweh’s “wonders” as connected with a prepared community and a God-centered order of movement: the ark, representing Yahweh’s covenant presence, leads the people into an unknown path (see the immediate setup in Joshua 3:3–4).
