Depending on what Bible you are using, Psalm 91 is often referred as the “Prayer for Security Under God’s Protection”, the “Psalm of Protection” or the “Soldier’s Psalm” or something along those lines.
All of the above titles seem appropriate as Psalm 91 emphasizes the theme of God’s protection and refuge for those who trust in Him. It speaks of God as a shelter from harm, a deliverer from various dangers, and a source of safety during times of trouble.
Psalm 91 is known for its comforting and reassuring message, assuring believers of God’s watchful care and the security they can find in their faith. It is a source of inspiration and solace for many during challenging times.
He will rescue you from the fowler’s snare,
from the destroying plague,
He will shelter you with his pinions,
and under his wings you may take refuge;
his faithfulness is a protecting shield.
You shall not fear the terror of the night
nor the arrow that flies by day,
Nor the pestilence that roams in darkness,
nor the plague that ravages at noon.
Though a thousand fall at your side,
ten thousand at your right hand,
near you it shall not come.
You need simply watch;
the punishment of the wicked you will see.
Because you have the LORD for your refuge
and have made the Most High your stronghold,
No evil shall befall you,
no affliction come near your tent.
For he commands his angels with regard to you,
to guard you wherever you go.
With their hands they shall support you,
lest you strike your foot against a stone.
You can tread upon the asp and the viper,
trample the lion and the dragon.
Because he clings to me I will deliver him;
because he knows my name I will set him on high.
He will call upon me and I will answer;
I will be with him in distress;
I will deliver him and give him honor.
With length of days I will satisfy him,
and fill him with my saving power.
