Psalm of Protection

The Lord is my light and my salvation—whom shall I fear?
The Lord is the stronghold of my life—of whom shall I be afraid?
When evil men advance against me to devour my flesh,
when my enemies and my foes attack me,
they will stumble and fall.
Though an army besiege me, my heart will not fear;
though war break out against me, even then will I be confident.
