Barn fi O Duw a dadleu'n dỳn(n)

Barn fi, O Duw, a dadleu'n dỳnn
  Yn erbyn pobloedd anwir:
Rhag y gwr twyllgar gwared fi
  A rhag drygioni'r dyhir.

Can's ti yw Duw fy nerth i gyd;
  Paham y'm bwrid ymaith?
A pha'm yr āf mor drwm a hyn,
  Gan bwys y gelyn diffaith?

Gyrr dy oleu, a moes dy wir,
  Ac felly t'wysir finnau;
Arweiniant fi i'th breswylf'ydd,
  I'th fynydd ac i'th demlau.

gwelir:
  O gyr dy oleu moes dy wir
  Tydi yw Duw fy nerth i gyd
  Ymddyrcha Dduw y nef uwchlaw

Judge me, O God, and argue tightly
  Against untrue peoples:
From the deceitful man deliver me
  And from the evil of the wicked.

Since thou art the God of all my strength;
  Why am I cast away?
And why do I go so heavy as this,
  With the weight of the wicked enemy?

Send thy light, and give thy truth,
  And thus to be led am I;
May they guide me to thy dwellings,
  To thy mountain and to thy temples.

1 Just Judge of heav'n, against my foes
    do thou assert my injured right;
  O set me free, my God, from those
    that in deceit and wrong delight.

2 Since thou art still my only stay,
    why leav'st thou me in deep distress?
  Why go I mourning all the day
    whilst me insulting foes oppress?

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.
