O ryfedd nerth y cadarn Iôr

O! ryfedd nerth y cadarn Iôr,
  Plyg anian ger ei fron;
Ei air yw deddf yr eang fôr,
  A'i amnaid ddofa'r dòn.

Wrth sŵn ei draed mynyddoedd ffŷ,
  Y bryniau gryma'u pen;
Gan ryfedd rym ei gorwynt cry'
  Y sigla seiliau'r nen.






Ymbwysa, f'enaid, ar ei nerth,
  Yn mhob rhyw 'storm a ddaw;
Fe'th arwain dros y rhiwiau serth
  I Salem yn ei law.

O wonderful strength of the steadfast Lord,
  Bow, nature, before him;
His word is the law of the wide sea,
  And his nod tames the wave.

At the sound of his feet mountains flee,
  The hills bow their head;
While the wonderful force of his strong hurricane
  Shakes the foundations of the sky.






Lean, my soul, on his strength,
  In every kind of storm that may come;
He leads thee across the steep hills
  To Salem in his hand.

Eternal Power, Almighty God,
  Who can approach thy throne?
Unfading light is thine abode,
  To mortal man unknown.

Before the radiance of thine eye,
  The heavens no longer shine;
And all the glories of the sky
  Are but the shade of thine.

Great God, and wilt thou condescend
  To cast a look below?
To this vile world thy notice bend, -
  These seats of sin and woe?

How strange, how wondrous, is thy love!
  With trembling we adore:
Not all th'exalted minds above,
  Its wonders can explore.

While golden harps and angel tongues
  Resound immortal lays,
Great God, permit our humble songs
  To celebrate thy praise.
