Who Would Have Thought?

Who would have thought that even an idle song
Were such a holy and celestial thing
That wickedness and envy cannot sing--
That music for no moment lives with wrong?
I know this, for a very grievous throng,
Dark thoughts, low wishes, round my bosom cling,
And, underneath, the hidden holy spring
Stagnates because of their enchantment strong.
Blow, breath of heaven, on all this poison blow!
And, heart, glow upward to this gracious breath!
Between them, vanish, mist of sin and death,
And let the life of life within me flow!
Love is the green earth, the celestial air,
And music runs like dews and rivers there!
