Darfu fy nerth 'rwy'n llwfrhau

Darfu fy nerth, 'rwy'n llwfrhau,
 Yn d'allu mae f'ymddiried;
Nerth mawr, difesur, fel y môr,
  Genyt sy'n stôr i'r gweiniaid.

Ti'm tynaist i o ganol tân,
  A mi o'r blaen yn ofni;
Gwna hyny eto'r fynyd hon,
  Mae f'enaid bron a threngu.

Mi bwysaf atat eto'n nes;
  Pa les im y ddigaloni?
Mae son am danat yn mhob man,
  Yn codi'r gwan i fyny.

Bydd coffa 'm danat ym mhob man
  I godi'r gwan i fyny;
Eu c'lonau'n demlau i Ti cair
  Sy wrth dy air yn crynu.

gwelir:
  Achub O Dduw fy enaid caeth
  B'le trof fy wyneb Arglwydd cu
  Dy ras yw'm gobaith O fy Nuw
  Mi nesaf atat etto'n nes

My strength is waning, I am wearied,
  In thy power is my trust;
Great, immeasurable strength like the sea,
  Thou hast as a store for the weak.

Thou hast pulled me from the midst of fire,
  Which I formerly feared;
Do this again this minute,
  My soul is almost expiring.

I will lean closer upon thee;
  Why should I be downhearted?
Telling about thee in every place, is
  Raising up the weak.

Memory about thee shall be in every place
  To raise the weak up;
Their hearts as temples to Thee are found
  Who at thy word are trembling.
