The Ammonites realized that they had made themselves offensive to David. So they hired the Arameans from Beth Rehob and Zobah (20,000 foot soldiers), ⌞the army of⌟ the king of Maacah (1,000 men), and the men of Tob (12,000 men).
The Egyptians are humans, not gods. Their horses are flesh and blood, not spirit. When the Lord uses his powerful hand, the one who gives help will stumble, and the one who receives help will fall. Both will die together.
