Was found no lie (ouch heurethē pseudos). First aorist passive indicative of heuriskō. In 1Pe 2:23 this passage (Isa 53:9) is quoted with dolos (deceit, guile) instead of pseudos (lie), but the difference is not great.
Without blemish (amōmoi). Alpha privative and mōmos (blemish, spot). As Christ the Paschal Lamb is (1Pe 1:19; Heb 9:14), so the followers of the Lamb are to be in the end (Phi 2:15).
