Luke 5:21
CA jah dugunnun þagkjan þai bokarjos jah Fareisaieis qiþandans: ƕas ist sa, saei rodeiþ naiteinins? ƕas mag afletan frawaurhtins, alja ains guþ?
— καὶ ἤρξαντο διαλογίζεσθαι οἱ γραμματεῖς καὶ οἱ φαρισαῖοι λέγοντες, τίς ἐστιν οὗτος ὃς λαλεῖ βλασφημίας; τίς δύναται ἁμαρτίας ἀφεῖναι εἰ μὴ μόνος ὁ θεός;
— And the scribes and the Pharisees began to reason, saying, Who is this which speaketh blasphemies? Who can forgive sins, but God alone?
