Am gael cynhaeaf yn ei bryd
  Dyrchafwn foliant byw;
Fe gyfoethogwyd meysydd byd
  Gan fendith afon Duw.

O ffynnon glir haelioni'r nef
  Y tardd yn hardd a byw;
Ac am ei fawr ddaioni Ef
  Y dywed afon Duw.

O! mor ddeniadol yw ei gwedd,
  Gan swyn o ddwyfol ryw:
Pelydra heulwen gras a hedd
  Ar dònau afon Duw.

O hon yr ŷf gronynnau'r llawr,
  A'r egin o bob rhyw:
Nid ydyw gemog wlith y wawr
  Ond dafnau afon Duw.

Pryd hau a medi a geir o hyd;
  Bendithir dynol-ryw
 gwenau'r nef, holl oesoedd byd,
  Trwy dawel afon Duw.

For having a harvest in its season
  Let us raise lively praise;
The world's fields have been enriched
  By the blessing of God's river.

O bright well of heaven's generosity
  The source beautiful and living;
And for His great goodness
  Speaks God's river.

O how attractive is thy countenance!
  With the charm of a divine kind:
Bright sunshine radiates grace and peace
  On the waves of God's river.

From this the earth's grains drink,
  And the shoots of every kind:
Nor is the jewelled dew of dawn
  But drops of God's river.

Time of sowing and reaping are still had;
  Humankind is being blessed
With heaven's smiles, all the world's ages,
  Through God's quiet river.
