Os rhodiwn y'ngoleuni gras

Os rhodiwn y'ngoleuni gras
  Cawn hoff gymdeithas Duwdod;
Gwaed Iesu Grist, rhinweddol yw,
  Er golchi pob rhyw bechod.

A dyma'r gwaed
    syddyn glanhau
  Pob ffiaidd fai a phechod;
Gwaed un Mab Duw,
    O ryfedd rin!
  Tawela'r flin gydwybod.

If we walk in the light of grace
  We get the lovely fellowship of Godhead;
The blood of Jesus Christ, virtuous it is,
  For washing every kind of sin.

And here is the blood
    which immediately cleanses
  Every detestable fault and sin:
The blood of the same Son of God,
    O wonderful virtue!
  Quietening the grieved conscience.
