O Frenin nef a daear lawr

O! Frenin nef a daear lawr
  Mor werthfawr yw Dy wedd!
Rho imi brawf ar hyn o bryd
  O'th nefol hyfryd hedd.

Goleua Di ein deall gwan
  Ym mhob rhyw ran o'th waith;
Amlyga 'nawr, i'th annwyl blant,
  Dy fawr ogoniant maith.

O cryned, Arglwydd, ger Dy fron
  Dy holl elynion cas,
A llwydda hefyd yma 'nawr
  Wirionedd mawr Dy ras.

Anwylaf Dad, O arddel Di
  Y genadwri hon
Nes llanwo gwir wybodaeth glau
  Holl gyrrau'r ddaear gron.

O King of heaven and earth below
  How precious is Thy countenance!
Give me an experience even now
  Of thy delightful, heavenly peace!

Lighten Thou our weak understanding
  In every kind of part of thy work;
Make evident now, to thy dear children,
  Thy great, vast glory!

O Lord, before thee may all
  Thy hateful enemies tremble,
And prosper also here, now,
  The great truth of Thy grace!

Dearest Father, O own Thou
  This message
Until true secure knowledge flood
  All the corners of the round earth!
