This is the Gorsedd Prayer which is part of the Bardic ceremony of the National Eisteddfod:

Dyro, Dduw, dy nawdd;
Ac yn nawdd, nerth,
Ac yn nerth, deall;
Ac yn neall, gwybod;
Ac yng ngwybod, gwybod y Cyfiawn;
Ac yng ngwyod y Cyfiawn, ei garu;
Ac a garu, caru pob hanfod;
Ac ym mhob hanfod, caru Duw,
Duw a phob Daioni.

And the translation that I have to hand - which seems to have managed to distance itself almost entirely from the poetry of the original:

Grant, O God, Thy protection;
And in protection, strength;
And in strength, understanding;
And in understanding, knowledge;
And in knowledge, knowledge of the Right;
And in knowledge of the Right, the love of it's essence;
And in the love of it's essence, the love of God,
God and all goodness.
