Fy Mugail yw'r Arglwydd (ni bydd arnaf byth)

Fy Mugail yw'r Arglwydd,
    ni bydd arnaf byth
Nac eisiau, na phrinder;
    caf lawnder dilyth,
  Gwna ef i mi orwedd
      mewn gwelltog borfeydd;
  Gerllaw dyfroedd tawel
      y'm tywys bob dydd.

Fe ddychwel fy enaid,
    fe'm harwain ar hyd
Hardd lwybrau cyfiawnder
    tra b'wyf yn y byd:
  Er mwyn ei wir enw,
      IOR enwog, y gwna;
  Can's mae fy Nuw yn ffyddlon
      yn dirion a da.

Dim niwed nid ofnwn,
    pe rhodiwn ar hyd
Glyn dwfn cysgod angau,
    ni laesai fy mryd;
  Can's gyda mi 'r ydwyt
      a'th wialen a'th ffòn,
  Y rhai a'm cysurant,
      a'm cadwant yn llon.

Daioni, trugaredd,
    dilynant fi'n glau
Holl ddyddiau fy mywyd,
    gan hyfryd barhau:
  Yn nhŷ y JEHOFA
      preswyliaf fi byth,
  Mewn hedd a chadernid,
      heb newid fy nyth.

My Shepherd is the Lord,
    I will never have
Either need, or scarcity;
    I will have endless fullness,
  He makes me lie
      in grassy pastures;
  Beside quiet waters
      he leads me every day.

He returns my soul,
    he leads me along
Beautiful paths of righteousness
    while I am in the world:
  For the sake of his true name,
      the renowned LORD, he does;
  For my God is faithful
      tender and good.

No change would I fear,
    if I travelled along
The deep shadowed vale of death,
    my heart would not droop;
  For with me thou art
      with thy rod and thy staff,
  Those which comfort me,
      and keep me cheerful.

Goodness, mercy,
    they will follow me surely
All the days of my life,
    enduring delightfully:
  In the house of JEHOVAH
      I will reside forever,
  In peace and security,
      without change of my nest.
