Hymns of the Atharva Veda, by Ralph T.H. Griffith, [1895], at sacred-texts.com
1We know the father of the shaft, Parjanya strong with hundred
    powers:
   By this may I bring health unto thy body: let the channels pour
    their burthen freely as of old.
 2We know the father of the shaft, Mitra, the Lord of hundred
    powers:
   By this, etc.
 3We know the father of the shaft, Varuna, strong with hundred
    powers: p. a4
   By this, etc.
 4We know the father of the shaft, the Moon endowed with
    hundred powers:
   By this, etc.
 5We know the father of the shaft, the Sun endowed with hundred
    powers:
   By this may I bring health unto thy body: let the channels pour
    their burthen freely as of old.
 6Whate'er hath gathered, as it flowed, in bowels, bladder, or in
    groins,
   Thus let the conduit, free from check, pour all its burthen as of
    old.
 7I lay the passage open as one cleaves the dam that bars the
    lake:
   Thus let, etc.
 8Now hath the portal been unclosed as, of the sea that holds the
    flood:
   Thus let, etc.
 9Even as the arrow flies away when loosened from the archer's
    bow,
   Thus let the burthen be discharged from channels that are checked
    no more.
