Though a host should encamp against me,
My heart shall not fear.
Though war should rise against me,
Even then will I be confident.
In the light of YHWH's presence with him nothing could stand against him. Whether it be an enemy encamped against him, and he had seen many of those, or whether it be open war, he had nothing to be afraid of, for his confidence lay in the One Who was mighty in battle, YHWH of hosts (Psalms 24:8; Psalms 24:10). In quietness and in confidence would be his strength (Isaiah 30:15). Our enemies may be of a different kind, especially the enemies of the soul (Ephesians 6:12), but the One Who is our light and our salvation will deliver us from them all as we clothe ourselves in His armour (Ephesians 6:10-18) and walk with Him (Matthew 10:28).
