After Israel ate the produce of the land, the manna ceased the next day Joshua 5:11–12. The text explains that Israel then ate the fruit of the land of Canaan instead of manna Joshua 5:12.
In Joshua 5:10–12, Israel camps at Gilgal near Jericho and observes Passover at the appointed time. The next day they begin eating food grown in the land—unleavened bread and roasted grain—rather than relying only on wilderness provisions. Immediately after they start eating the land’s produce, the manna stops. This scene sits just after Israel’s crossing of the Jordan and their first days on the west side (Joshua 3–4). Chapter 5 slows down the battle storyline to show Israel being re-formed as a covenant community before major conflict begins.
Joshua 5:10–12 presents a short, carefully timed sequence: Israel is now camped at Gilgal near Jericho, they keep Passover on its set date, and immediately afterward their food source changes. Explicitly, they eat “produce of the land” the day after Passover (named as unleavened cakes and roasted grain), and then manna stops the next day.
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Joshua 5:11-12, then read the surrounding section so the answer stays connected to the passage's flow.
11They ate of the produce of the land on the next day after the Passover, unleavened cakes and parched grain, in the same day.
12The manna ceased on the next day, after they had eaten of the produce of the land; neither had the children of Israel manna any more; but they ate of the fruit of the land of Canaan that year.
