Overshadowed by God is Psalm 91. It describes the result of a person overshadowed by God:
4 He shall overshadow you with His shoulders, And under His wings you shall hope; His truth shall encircle you with a shield…
10
Evils shall not come to you,
And a scourge shall not draw near your dwelling;
11
For He shall command His angels concerning you,
To keep you in all your ways;
12
In their hands they shall bear you up,
Lest you strike your foot against a stone;
13
You shall tread upon the asp and the basilisk,
And you shall trample the lion and the dragon….
15
He shall call upon Me, and I will hear him;
I am with him in affliction,
And I will deliver and glorify him.
16
With length of days I will satisfy him,
And show him My salvation.”
