O Iôr Preswylydd mawr y berth

O! Iôr, Preswylydd mawr y berth -
Y ffynnon fawr o râs a nerth!
  Rho ynof lef, a chlyw fy nghŵyn -
  Dy iau a'th groes,
      dysg im' eu dwyn.

Os rhaid im' beunydd ddwyn y groes,
Tra pery gyrfa fer fy oes,
  O Arglwydd! dyro help Dy fraich,
  I gynnal eiddil dàn ei faich.

Mewn cyfyngderau, sâf o'm plaid,
Yn gadarn Dŵr, a nerth wrth raid;
  Yn Dad, yn Frawd, yn Briod bydd,
  Hyd angeu, a thrwy fythol ddydd!

Os Ti'm gadewi, Iesu mawr,
Y lleiaf peth a'm teifl i lawr;
  Ond er y 'storm a'r tònau maith,
  Dof yn dy law
      i ben fy nhaith.

O Master, great inhabitant of the bush -
The great found of grace and strength!
  Put in me a cry, and hear my complaint -
  Thy yoke and thy cross,
      teach me to carry them.

If I must daily carry the cross,
While the short course of my age endures,
  O Lord, give the help of thy arm,
  To support the weak under his burden.

In straits, stand on my side,
As a firm Tower, and strength in need;
  As Father, as Brother, as Spouse be thou,
  As far as death, and through eternal day!

If Thou leave me, great Jesus,
The smallest thing shall cast me down;
  But despite the storm and the vast waves,
  I shall come by thy hand
      to my journey's end.
