Middleton’s psalms remained at the British Library, where they came to the attention of Walter Davies. Rev. Walter Davies (1761-1849) was a Welsh poet, editor, translator, antiquary and Anglican clergyman, born in Llanfechain, Montgomeryshire. He studied at Trinity College, Cambridge, where he received his M.A. in 1803. As a poet he used the bardic name of Gwallter Mechain. In 1807 he became vicar of Manafon, where he remained for 30 years and did most of his literary work. From there he wrote an introduction ("Y Rhagymadrodd") to the Middleton psalms in January 1827, and explained about their poetry. He arranged for them to be published by Robert Jones in Llanfair Caereinion in Montgomeryshire in 1827. He reprinted them as "Psalmau Dafydd: wedi eu cyfansoddi ar amrywiol fesurau cerdd, gan Y Cabden William Middleton". This was called the Second Edition ("Ail Argraphiad").
