Mae ffyn(n)on hyfryd lawn o waed

Mae ffynon hyfryd lawn o waed
  A redodd ar y bryn:
Y pechaduriaid duaf gaed
  A olchir ynddi'n wỳn.

Bu'r lleidr aflan un prydnawn
  Yn edrych arni'n llon:
A minnau olchir sydd yn llawn
  Mor frwnt ag ef yn hon.

gwelir:
  Agorwyd fynnon i'n glanhau
  Mae ffynnon lān fy enaid cred
  Mi welaf ffynnon lawn o waed

There is a delightful fount full of blood
  Which ran on the hill:
The blackest sinners there are
  Are to be washed in it white.

The unclean thief one afternoon
  Looked upon it cheerfully:
And I too am to be washed who is fully
  As filthy as he in this.

There is a fountain filled with blood
  Drawn from Emmanuel's veins;
And sinners plunged beneath that flood
  Lose all their guilty stains.

The dying thief rejoiced to see
  That fountain in his day;
And there may I, though vile as he,
  Wash all my sins away.
