O Dduw ein tarian cawsom di

O Dduw ein tarian, cawsom Di
  I'n nerthu yn y brwydrau;
O! diosg eto'r fraich a fu
  O'n tu mewn cyfyngderau.

A rho i ninnau ras parhau
  I gadw'n harfau'n loywon,
Nes llwyr orchfygu,
    er dy glod,
  Eilunod ein gelynion.

Bydd eto'n darian in, O! Dduw,
  Er cryfed yw'r elyniaeth;
O wisgo dy arfogaeth lawn
  Cawn gyflawn fuddugoliaeth.

A phan ddaw'r brwydro hir i ben
  Bydd llawen orfoleddu,
Ac uno yn y nefol gân
  I'r Duw fu'n darian inni.

O God our shield, we had thee
  To strengthen us in the battles;
O bare again thy arm that was once
  On our side in straits.

O grant to us enduring grace
  To keep our weapons bright,
Until completely overcoming,
    for thine acclaim,
  The idols of our enemies.

Be still a shield to us, O God!
  Despite how strong is the enmity;
From wearing thy full armour
  We may get a full victory.

And when the long battling comes to an end
  There shall be joyful rejoicing,
And joining in the heavenly song
  To the God who was a shield to us.
