Exodus 8:19

וַיֹּאמְר֤וּ הַֽחַרְטֻמִּים֙ אֶל־פַּרְעֹ֔ה אֶצְבַּ֥ע אֱלֹהִ֖ים הִ֑וא וַיֶּחֱזַ֤ק לֵב־פַּרְעֹה֙ וְלֹֽא־שָׁמַ֣ע אֲלֵהֶ֔ם כַּאֲשֶׁ֖ר דִּבֶּ֥ר יְהוָֽה׃ ס

εἶπαν οὖν οἱ ἐπαοιδοὶ τῷ Φαραώ Δάκτυλος θεοῦ ἐστὶν τοῦτο· καὶ ἐσκληρύνθη ἡ καρδία Φαραώ, καὶ οὐκ εἰσήκουσεν αὐτῶν, ἐλάλησεν κύριος.

“ This is the finger of God,” the magicians said to Pharaoh. But Pharaoh’s heart was hardened, and he would not listen to them, just as the LORD had said. The Fourth Plague: Flies
