- c. 800–825, Diarmait, Milan Glosses on the Psalms, published in Thesaurus Palaeohibernicus (reprinted 1987, Dublin Institute for Advanced Studies), edited and with translations by Whitley Stokes and John Strachan, vol. I, pp. 7–483, Ml. 55^d11
  Amal du·berad nech hi ceist do Dauid: “Húare is móir sléb fírinne Dǽ, cid ara fodmai-siu, ⟨a⟩ Dauid, didiu a ndu imnedaib ⁊ frithoircnib fo·daimi? Air it fírían-⟨s⟩u.” Ícaid-som didiu anísin, a n‑as·mbeir iudicia Domini abisus multa .i. ataat mesai Dǽ nephchomtetarrachti amal abis ⁊ amal fudumain. Is ed in sin fod·era in n‑erígim, cid ara fodaim int aís fírían inna fochaidi, ⁊ cid ara mbiat in pecthaig isnaib soinmechaib.
  As though someone had put as a question to David: “Because God’s righteousness is as great as a mountain, why then, David, dost thou suffer what of afflictions and injuries thou sufferest? For thou art righteous.” He solves that then when he says “iudicia Domini abyssus multa”, i.e. there are judgments of God incomprehensible like an abyss and like a depth. That is what causes the complaint why the righteous folk endure tribulations, and why sinners are in prosperity.
