II Samuel 22:35

We were troubled on every side; without were fightings, within were fears.—Fear not: for they that be with us are more than they that be with them.—Strong in the Lord, and in the power of his might.

Thou comest to me with a sword, and with a spear, and with a shield: but I come to thee in the name of the Lord of hosts, the God of the armies of Israel, whom thou hast defied.—God is my strength and power: . . . he teacheth my hands to war; so that a bow of steel is broken by mine arms.—Our sufficiency is of God.
