Proverbs 21:31

For Solomon, his horses were like today’s tanks. (Tanks are strong, powerful, army vehicles.) A horse was strong and fast in a battle. It could pull a chariot (vehicle) or carry a soldier. The enemy was afraid of the horses.

Horses need food, water and exercise. Soldiers trained the horses for the battle. But the strength of the horses could not win the battle. A large, powerful army does not always win the war, even today. God decides who wins. See 1 Samuel 14:6-15; Joshua 5:13-6 and 1 Samuel 17.
