How beautiful upon the mountains are the feet of him that bringeth good tidings, that publisheth peace; that bringeth good tidings of good, that publisheth salvation; that saith unto Zion, Thy God reigneth!
How beautiful upon the mountains are the feet of him that bringeth good tidings - i:e., The advent of such a herald seen on the distant "mountains" (notes, Isaiah 40:9; Isaiah 41:27; Isaiah 25:6-7; Song of Solomon 2:17), running in haste with the long-expected good tidings, is most grateful to the desolated city (Nahum 1:15).
Good tidings ... that saith unto Zion, Thy God reigneth - only partially applying to the return from Babylon. Fully and antitypically, the Gospel (Luke 2:10-11), "beginning at Jerusalem," (Luke 24:47), "the city of the great King" (Matthew 5:35), where Messiah shall, at the final restoration of Israel, 'reign' as peculiarly Zion's God ("Thy God reigneth:" cf. Psalms 2:6).
