    Na foed it dduwiau ond Myfi (Ioan Rhys)

 1. Do not have gods except Me,
 2. Worship no idol.

 3. Do not vainly take the name of God,
 4. Do not desecrate the Sabbath, it is holy.

 5. Give to thy parents reverence and respect,
 6. Commit no murder, shun it.

 7. Keep from an unclean word or deed,
 8. Despite poverty do not steal either.

 9. Do not be, nor love being lying,
10. Do not covet
        the possession of thy neighbour.

Thou shalt have no other gods but Me;
Before no idol bow thy knee.

Take not the Name of God in vain;
Nor dare the Sabbath Day profane.

Give both thy parents honour due;
Take heed that thou no murder do.

Abstain from words and deeds unclean;
Nor steal, though thou art poor and lean.

And do not lie, but always say what is true,
And covet not
    the things that don't belong to you!
