Bible Verses About Warfare of Saints: With confidence in God

¶ A Psalm of David. The LORD is my light and my salvation; whom shall I fear? the LORD is the strength of my life; of whom shall I be afraid?

When the wicked, even mine enemies and my foes, came upon me to eat up my flesh, they stumbled and fell.

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