Wel dyma'r ddeddf, medd Iesu mad,
  'R hon gan fy Nhad a glywais;
Ti yw fy Mab, o'm perffaith ryw,
  A heddyw y'th genhedlais.

Gofyn, fy Mab, a'th Dad a rydd
  Y gwledydd oll i'th feddiant;
A holl genhedloedd daear gron,
  O'r bron, dy eiddo fyddant.

Gwas'naethwch mwy Etifedd nef,
  Ac ofnwch ef yn wastad;
Ymlawenhêwch dan grynu i gyd,
  Trwy'r byd, yng Nghrist eich Ceidwad.

Y Mab cusenwch, rhag ei ddig,
  A'ch bwrw'n ffyrnig heibio;
Can's gwyn ei fyd y sawl a gred,
  Ac a ymddiried ynddo.

See, here is the decree, says esteemed Jesus,
  The one I heard from my Father;
Thou art my Son, of my perfect kind,
  And today I have begotten thee.

Ask, my Son, and thy Father will give
  All the lands for thy possession;
And all the nations of the round earth,
  Completely, thy property they will be.

Serve ye henceforth the Heir of heaven,
  And fear him constantly;
Take delight, while trembling altogether,
  Through the world, in Christ your Saviour.

Kiss the Son, lest ye anger him,
  And he cast you furiously away;
Since blessed is any who believes,
  And trusts in him.
