Even as YHWH established reverence in the hearts of His people, as He made it clear that obedience was not an option, but the only way to bring about the fulfillment of the promises made to Israel, to take, fill, and be fruitful in the land of promise. Here, in this episode, following the one of judgment and remembrance, God walks Israel through the victory they will have over Ai, the treasures that were to be theirs, and how it will be accomplished. This is a recurring theme as God expands His glory through His people - He reveals the designs of dominion, not only to outline how things will be, but as another support or proof of His being present in our battle. The Great Commission is such a plan - how to accomplish the mission and objective which God promises to be fulfilled. We can rest both in the plan and the fulfillment of it as both are given by God.
