Hide not Your face from me; turn not Your servant away in anger,  
You Who have been my help!
Cast me not off, neither forsake me, O God of my salvation!
Psalm 27:9 (Amplified Bible) 

The Lord is my Strength and my [impenetrable] Shield; 
my heart trusts in, relies on, and confidently leans on Him, and I am helped; 
therefore my heart greatly rejoices, and with my song will I praise Him.
Psalm 28:7 (Amplified Bible)
