O Arglwydd bendigedig

O Arglwydd bendigedig,
  Ti ydyw'r Meddyg mawr,
Ti fu'n rhoi bôd i'r bydoedd,
  A lluoedd nef a llawr;
Tydi sy'n cynnal iechyd
  A bywyd ymhob un;
I ti boed y gogoniant, -
  Dy haeddiant it' dy hun.

O blessed Lord,
  Thou art the great Physician,
Thou didst give being to the worlds,
  And the hosts of heaven and earth;
Thou dost maintain the health
  And life of every one;
To thee be the glory, -
  Which thou thyself deservest.
