Matthew 5:47
CA jah jabai goleiþ þans frijonds izwarans þatainei, ƕe managizo taujiþ? niu jah motarjos þata samo taujand?
— καὶ ἐὰν ἀσπάσησθε τοὺς ἀδελφοὺς ὑμῶν μόνον, τί περισσὸν ποιεῖτε; οὐχὶ καὶ οἱ ἐθνικοὶ τὸ αὐτὸ ποιοῦσιν;
— And if ye salute your brethren only, what do ye more than others? do not even the publicans so?
