Exodus 7:22
JPS-1917וַיַּֽעֲשׂוּ־כֵ֛ן חַרְטֻמֵּ֥י מִצְרַ֖יִם בְּלָטֵיהֶ֑ם וַיֶּחֱזַ֤ק לֵב־פַּרְעֹה֙ וְלֹא־שָׁמַ֣ע אֲלֵהֶ֔ם כַּאֲשֶׁ֖ר דִּבֶּ֥ר יְהֹוָֽה׃
And the magicians of Egypt did in like manner with their secret arts; and Pharaoh’s heart was hardened, and he hearkened not unto them; as the LORD had spoken.
Rashi Commentary
בלטיהם SECRET ARTS — magic formulas which they utter secretly and in a whisper. Our Rabbis stated that בלטיהם refers to the work of demons, בלהטיהם to witchcraft (Sanhedrin 67b; Exodus Rabbah 9:11). ויחזק לב פרעה AND PHARAOH’S HEART WAS HARDENED so that he said: You are doing this by witchcraft: “You are bringing straw to Afarayim”— a city that is full of straw; thus you bring sorcery to Egypt, a land that is full of sorcery (Menachot 85a; Exodus Rabbah 9:6-7).
