2 “My servant Moshe is dead. Prepare to cross the Yarden, together with all this people, into the land that I am giving to the Israelites.

1:2 Prepare to cross the Yarden

Jordan River
Hashem instructs Yehoshua, the new leader of the Nation of Israel, to rise up and lead them across the Yarden, and to inhabit the land that Hashem is giving them. Taking possession of Eretz Yisrael will require human actions, which will be supported by God’s miracles. At the very beginning of Yehoshua’s leadership, the nation is reminded that the entire Eretz Yisrael belongs to the Jewish people, and that they must do their part to take possession of this special gift from Hashem.
It’s interesting that in the first exodus Moses stretched forth His arm and the supernatural power of God parted the waters. Now it is as the feet of the priests in the river are the means of supernatural power exerted by God again upon water, yet it indicates that this new way would have to be walked out. Every place that the sole of your foot shall tread shall be yours.
