1 Samuel 19:8

It is God that girdeth me with strength, and maketh my way perfect. He maketh my feet like hinds' feet, and setteth me upon my high places. He teacheth my hands to war, so that a bow of steel is broken by mine arms. Thou hast also given me the shield of thy salvation: and thy right hand hath holden me up, and thy gentleness hath made me great. Thou hast enlarged my steps under me, that my feet did not slip. I have pursued mine enemies, and overtaken them: neither did I turn again till they were consumed. I have wounded them that they were not able to rise: they are fallen under my feet. For thou hast girded me with strength unto the battle: thou hast subdued under me those that rose up against me. Thou hast also given me the necks of mine enemies; that I might destroy them that hate me. They cried, but there was none to save them: even unto the LORD, but he answered them not. Then did I beat them small as the dust before the wind: I did cast them out as the dirt in the streets. Thou hast delivered me from the strivings of the people; and thou hast made me the head of the heathen: a people whom I have not known shall serve me. As soon as they hear of me, they shall obey me: the strangers shall submit themselves unto me. The strangers shall fade away, and be afraid out of their close places. The LORD liveth; and blessed be my rock; and let the God of my salvation be exalted. It is God that avengeth me, and subdueth the people under me. He delivereth me from mine enemies: yea, thou liftest me up above those that rise up against me: thou hast delivered me from the violent man. Therefore will I give thanks unto thee, O LORD, among the heathen, and sing praises unto thy name. Great deliverance giveth he to his king; and sheweth mercy to his anointed, to David, and to his seed for evermore.

Though an host should encamp against me, my heart shall not fear: though war should rise against me, in this will I be confident.
