Being Covered

"I got you covered. I got your back"

I sometimes read or hear that, and it generally applies in situations where one is more or less in distress, and another one is being reassuring, as if saying, "Hey, I'm your friend. You can count on me. I'm vouching for you."

The following sequence of verses makes me think of that:

"But now, this is what the Lord says--He who created you, O Jacob,
 He who formed you, O Israel:
 'Fear not, for I have redeemed you; I have summoned you by name; you are Mine. 
 When you pass through the waters, I will be with you; 
 and when you pass through the rivers, they will not sweep over you.
 When you walk through the fire, you will not be burned. The flames will not set you ablaze.'" Isaiah 43:1-2
