Pass through the host, and command the people, saying, Prepare you provisions; for within three days you shall pass over this Jordan, to go in to possess the land, which the LORD your God gives you to possess it.
All Commentaries on Joshua 1:11 Go To Joshua 1
Caesarius of Arles
AD 542
For this reason Joshua said to the people, “Prepare your provisions for the journey.” Today, if you willingly listen, Christ our Lord says to you, “If you will follow me, prepare food for the journey.” This food is good works which accompany us like faithful food for the journey to future bliss. Therefore, consider, brothers, that if each one does not prepare food for himself, he cannot follow Joshua when he enters the land of promise.
