Tydi O Dduw wyt ffynnon lawn

Tydi, O Dduw, wyt ffynnon lawn,
Trysordy pob rhyw
    nefol ddawn:
  O! gad i mi fwynhau Dy hedd,
  A phara'n ffyddlon hyd fy medd.

Dy ddwyfol nerth, O! dod i mi,
Fel gallwyf aros ynot Ti;
  A llanw fi â'th gariad drud
  Nes dod i'r làn i'r nefol fyd.

Thou, O God, art a full fount,
A treasure house of every kind
    of heavenly gift:
  O let me enjoy Thy peace,
  And continue faithful until my grave.

Thy divine strength, O give to me,
Thus I may remain in Thee;
  And flood me with thy precious love
  Until coming up to the heavenly world.
