Dy oleu cu a dy wirionedd moes

Dy oleu cu,
    a dy wirionedd moes,
I'm tywys mwy,
    a'm harwain trwy fy oes;
  Nes dof i'r lan
      i dawel orphwys fry,
  Ar Sïon fryn,
      ac yn dy sanctaidd dŷ.

Ac yna'r af
    yn llon at allor Duw,
At Dduw yr hwn
    fy holl orfoledd yw;
  I Dduw, fy Nuw,
      y canaf beraidd glod,
  Ar delyn aur,
      tra nefoedd wen yn bod.

Thy dear light,
    and thy truth, give!
To lead me evermore,
    and guide me throughout my lifespan;
  Until I come up
      to a quiet rest above,
  On Zion hill,
      and in thy holy house.

And there I shall go
    cheerfully to God's altar,
To God, him who
    all my rejoicing is;
  To God, my God,
      I shall sing sweet praise,
  On a golden harp,
      while ever bright heavens are being.

3 Let me with light
      and truth be blest,
    be these my guides,
        and lead the way
  Till on thy holy
      hill I rest,
    and in thy sacred
        temple pray.

4 Then will I there
      fresh altars raise
    to God, who is
         my only joy;
  And well tuned harps,
      with songs of praise,
    shall all my
        grateful hours employ.
