Here is my attempt at the second verse…
Your faith was strong but you needed proof
Oedd dy ffydd di’n cryf ond mae isia prawn i’ti
You saw her bathing on the roof
Gwelai’ti ymdrochi ar yr to
Her beauty and the moonlight overthrew you
Ei harddwch a yr lloergan 'di ddymchwel i’ti
She tied you to her kitchen chair
Mae hi’n glymu ti i ei gadeirydd gegin i
She broke your throne and she cut your hair
Dorrodd hi dy orsedd di a oedd hi’n torri dy gwallt di
And from your lips she drew the Hallelujah
Ac o dy gwyfusiau di tynnodd o’r Halelwia
