Even though the Arameans had more soldiers, Israel won a great victory with God's help. Everyone learned that "nothing is impossible with God" (Luke 1:37; see Matthew 19:26; Mark 10:27). When God supports you, the enemy will retreat (Psalm 56:9) and suffer heavy losses (Deuteronomy 32:30–31; 2 Kings 19:32–36). Israel could face their enemies without fear (Psalms 3:6; 27:1–3).
God's promise to Israel through the prophet showed that this battle was for both Israel's safety and the Lord's glory.
