O Arglwydd Dduw Jehofa cu

O Arglwydd Dduw, Jehofa cu,
Gwir deilwng wyt o'n moliant ni;
  Dy enw mawr a folir fry,
  Yn wresog gan y nefol lu.

Dymunwn ninau, Arglwydd, Iôr,
Gyduno'n awr â'r nefol gôr;
  A chalon bur, trwy lafar lef,
  Addoli'n barchus Frenin nef.

Gwaith hyfryd iawn yw moli Duw,
Gwaith pur a santaidd hefyd yw;
  Dy Ysbryd Glân, O Arglwydd mawr,
  Yn gymorth i ni, dyro'n awr.

O Lord God, dear Jehovah,
Truly worthy thou art of our praise;
  Thy great name is to be praised above,
  Warmly by the heavenly host.

We also wish, Sovreign Lord,
To join now with the heavenly choir;
  With a pure heart, through a vocal voice,
  Worshipping reverently the King of heaven.

Very delightful work is praising God,
Pure and holy work it is;
  Thy Holy Spirit, O great Lord,
  As a help to us, give now!
