Before engaging in battle, Israel pauses for spiritual preparation. The men are circumcised, renewing the covenant sign that had been neglected during the wilderness years. The Passover is celebrated, commemorating God's deliverance from Egypt and anticipating the conquests ahead. In a mysterious encounter, Joshua meets the "commander of the Lord's army," before whom he removes his sandals on holy ground—reminiscent of Moses' burning bush experience. This divine encounter establishes that the coming victories belong to God, not human military prowess. Similarly, our spiritual battles require proper consecration and the recognition of God's leadership before we engage.
