A.1 For, behold, the day cometh, that shall burn (baar) as an oven;

B. and all the proud, yea, and all that do wickedly, shall be stubble:

A’. and the day that cometh shall burn (lahat) them up, saith the LORD of hosts,

B’. that it shall leave them neither root nor branch.

A.2 But unto you that fear my name shall the Sun of righteousness arise with healing in his wings;

B. and ye shall go forth, and grow up as calves of the stall.

B’. 3 And ye shall tread down the wicked; for they shall be ashes under the soles of your feet

A’. in the day that I shall do this,  saith the LORD of hosts.

Note: in these  two sections the day of judgment for the wicked is contrasted with the day of salvation for the righteous. Special emphasis is given to the latter,  with “the  coming of the day” described as the rising of the sun of righteousness, i.e. the coming of Christ.
