Just before the historic crossing of the Jordan River, the Israelites stand at a pivotal transition. They are required to shift from a reality of daily miracles in the desert to a state of practical, natural preparation as they get ready to inherit the land. This transition begins with a structured chain of command. Joshua delivers his orders to a messenger, who passes them down to the officers. These officers then instruct the people, ensuring the message is shared from person to person throughout the camp [אלשיך].
The core of these orders focuses on gathering provisions, organizing logistics, and packing for the road ahead [מצודת ציון, ביאור שטיינזלץ]. Because the Israelites were still eating the miraculous manna that fell in the desert, the exact nature of these preparations is a matter of discussion. One perspective is that the instructions did not involve food at all, but rather the gathering of weapons and military equipment for the upcoming battles [רש״י]. Another viewpoint suggests the exact opposite: the command specifically required food and not weapons in order to encourage the nation. By focusing on food, the leadership signaled that the land was already prepared for them, removing the need for standard military anxiety [חומת אנך].
Within the understanding that the people were indeed preparing food, different methods are proposed. Some explain that the preparation involved the manna itself, which had to be ground and pounded to be ready for the march [מלבי״ם, ביאור שטיינזלץ]. Others maintain that the provisions consisted of new types of food, such as meat or local crops purchased from merchants in the area [רד״ק, מצודת דוד, ביאור שטיינזלץ]. The requirement to prepare natural food, even while the manna was still available, served as a vital lesson that the nation must now take practical steps and no longer rely on miracles [חומת אנך].
The timeline for this movement dictates that the crossing would occur at the end of three full days of preparation, rather than at some unspecified moment during that window [רש״י, רד״ק, מצודת ציון, רלב״ג]. From a chronological standpoint, these orders were issued only after the spies returned from their mission to Jericho. Because their scouting mission lasted three days, the actual movement toward the Jordan River could only begin once they had safely returned to the camp [מצודת דוד].
