Bible Verses About Warfare of Saints: With confidence in God

Jehovah is my light and my salvation; Whom shall I fear? Jehovah is the strength of my life; Of whom shall I be afraid?

When evil-doers came upon me to eat up my flesh, Even mine adversaries and my foes, they stumbled and fell.

Though a host should encamp against me, My heart shall not fear: Though war should rise against me, Even then will I be confident.
