Charles Ellicott Commentary Malachi 4:2

"But unto you that fear my name shall the sun of righteousness arise with healing in its wings; and ye shall go forth, and gambol as calves of the stall." — Malachi 4:2 (ASV)

As the rising sun diffuses light and heat, so that all that is healthy in nature revives and lifts up its head, while plants that have no depth of root are scorched up and wither away, so the advent of the reign of righteousness, which will reward the good and the wicked, each according to their deserts, will dissipate all darkness of doubt, and heal all the wounds which the apparent injustice of the conduct of affairs has inflicted on the hearts of the righteous.

Wings. —Figurative for rays. The fathers and early commentators have understood the Sun of Righteousness to refer to Christ, and they are correct in that it is the period of His advent that is referred to; but there can be no personal reference to Him in the expression, since “sun” is feminine in Hebrew; and the literal rendering of the word translated “in his wings” is “in her wings.”

Grow up. —Better, prance, or sport.
