Healing in his wings

"For behold, the day is coming,
Burning like an oven,
And all the proud, yes, all who 
do wickedly will be stubble.
And the day which is coming 
shall burn them up,"
Says the LORD of hosts,
"That will leave them 
neither root nor branch.
But to you who fear My name
The Sun of Righteousness shall arise
With healing in His wings;
And you shall go out
And grow fat like stall-fed calves.
You shall trample the wicked,
For they shall be ashes under the 
soles of your feet
On the day that I do this"
Says the LORD of hosts.

Malachi 4:1-3
