Wele'n dyfod ar y cwmwl (Yn ei fawredd ... )

Wele'n dyfod ar y cwmwl
  Yn ei fawredd, Frenin nef;
Heirdd gerubiaid a seraffiaid
  Fyrdd o gylch ei orsedd Ef:
    Sŵn yr udgorn,
  Egyr gedyrn byrth y bedd.

Mil o filoedd, myrdd myrddiynau,
  O gwmpeini hardd eu gwedd,
Welir draw yn codi fyny
  I'w gyfarfod Ef o'r bedd:
    Dyma'r bore,
  Gwelir Seion oll yn rhydd.

gwelir: :Nid oes yno gofio beiau

See, coming on the cloud
  In his greatness, the King of heaven;
Splendid cherubim and seraphim
  A myriad around His throne:
    The sound of the trumpet,
  Opens the strong portals of the grave.

A thousand thousands, a myriad myriads,
  Of a company of beautiful countenance.
To be seen yonder rising up
  To meet Him from the grave:
    Here is the morning,
  Zion to be seen all free.

Lo! He comes on clouds of glory,
  Circled by an angel-throng
Who proclaim His lofty titles
  With their trumpets, loud and long.
    Hallelujah,
  Welcome, welcome, Son of Man!

Thousand thousands, myriad myriads
  Bright attendants on the Lord,
See I rising from corruption,
  At the mighty signal-word:
    Farewell, sadness,
  Full redemption now is come.

Lo he cometh countless trumpets
