Amlyga Di O Arglwydd Iôr

Amlyga Di, O! Arglwydd Iôr,
  O fôr i fôr, dy fawredd;
A dangos i holl ddynol-ryw
  Mor union yw'r gwirionedd.

Llefara wrthym air mewn pryd,
  Dod ysbryd in i'th garu;
Datguddia inni'r oedfa hon
  Ogoniant person Iesu.

O! Arglwydd Dduw, 'r Hwn biau'r waith,
  Arddel dy faith wirionedd,
Fel byddo i bechod, o bob rhyw
  Gael marwol friw o'r diwedd.

  O Arglwydd Dduw 'r Hwn biau'r waith

Reveal, O Sovereign Lord,
  From sea to sea, thy greatness;
And show to the whole of humankind
  How straight is the truth.

Speak to us a word in season,
  Come, Spirit, for us to love thee;
Reveal to us during this service
  The glory of the person of Jesus.

O Lord God, whose is the work,
  Own thy vast truth,
So that sin, of every kind, may
  Get a mortal wound eventually.
