By strength shall no man prevail. -- I SAM.2:9.

Then said David to the Philistine, 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. And David put his hand in his bag, and took thence a stone, and slang it. So David prevailed over the Philistine with a sling and with a stone.

There is no king saved by the multitude of an host: a mighty man is not delivered by much strength. Behold, the eye of the Lord is upon them that fear him, upon them that hope in his mercy. -- Both riches and honour come of thee, and thou reignest over all; and in thine hand is power and might; and in thine hand it is to make great, and to give strength unto all.

I glory in my infirmities, that the power of Christ may rest upon me. Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong.
