Moses set up an army of faith.
When the Amalekites went to war against the Israelites, Moses, Aron, and Hur went to the top of the hill, and as Moses lifted up his hands unto the heavens, the Israelites conquered the Amalekites.
Exodus 17 vs 8 - 16
Moses, rather than believing in weapons of war, he trusted in God as the only one that can guarantee victory, therefore, he lifted hands to the throne of God.
The benefits of the type of army set up by Moses is that victory is always guaranteed because God does not fight a battle and lose.
The army is modeled after Faith in in God, not on bears, arrow, or tactics.
