Ffrydiau tawel byw rhedegog

Ffrydiau tawel, byw, rhedegog,
  O tàn riniog
      tŷ fy Nuw,
Sydd yn llanw ac yn llifo
  O fendithion o bob rhyw;
Dyfroedd gloyw fel y grisial
  I olchi'r euog, nerthu'r gwan,
Ac a gana'r
    Ethiop dua'
  Fel yr eira, yn y man.

O am yfed yma beunydd
  Ffrydiau'r iechydwriaeth fawr,
Nes fy nghwbl ddisychedu
  Am wiwedig bethau'r llawr:
Môr didrai o bob trugaredd
  Ydyw'r iechydwriaeth lawn,
Lanwod ac a lifodd allan
  Ar Galfaria un prydnawn.

gwelir:
  O rhwyga'r tew gymylau duon
  Pechadur aflan yw fy enw
  Rhwyga'r tew gymylau duon

Quiet, living, running streams,
  From under the threshold
      of my God's house,
Are flooding and flowing
  With blessings of every kind;
Bright waters like the crystal
  To wash the guilty, strengthen the weak,
And which will bleach the
    blackest Ethiopian
  Like the snow, soon.

O to drink here daily
  The stream of great salvation,
Until my thirst is completely quenched
  For the vacillating things of earth:
So unebbing of every mercy
  Is the full salvation,
That flooded and flowed out
  On Calvary one afternoon.
