Hello! I have found the lyrics for the sequence "houses of healing", if soeone is interested. It is a part of "the grace of the Valar".
The words are:
Immen d˙ath caeda, - Shadow lies between us,
Sui tollech omen, - as you came to us, (im not sure of this part but it almost sounds like it is correct. The actual line is "Sui tollech, tami gwannathach omen" and translates "As you came, so you shall leave from us".)
Boe naid bain gwannathar, - All things must pass away,
Boe cuil ban firitha. - All life is doomed to fade.
