I Dduw rhowch foliant clau

I Dduw rhowch foliant clau
  Yn uchelderau'r nef:
Cerubiaid a Seraphiaid llon,
  Angylion molwch Ef.

Holl fawrion daear dowch,
  Cynghanedd rhowch yn nghyd;
Gan foli'r dyrchafedig Dduw,
  Tra byddoch byw'n y byd.

Yn siriol doed y saint,
  Am eu rhagorfraint fawr:
Gwir Israel Duw sydd īs y nef,
  Molienwch Ef yn awr.

To God give true praise
  In the heights of heaven:
Cheerful cherubs and Seraphs,
  Angels praise ye Him.

All ye great ones of the earth, come,
  Render harmony together;
In praising the exalted God,
  While ever ye live in the world.

Cheerfully let the saints come,
  For their great privilege:
The true Israel of God which is under heaven,
  Praise Him now.
