(יב) וַיֹּ֣אמֶר יְהוָה֮ אֶל־מֹשֶׁה֒ אֱמֹר֙ אֶֽל־אַהֲרֹ֔ן נְטֵ֣ה אֶֽת־מַטְּךָ֔ וְהַ֖ךְ אֶת־עֲפַ֣ר הָאָ֑רֶץ וְהָיָ֥ה לְכִנִּ֖ם בְּכָל־אֶ֥רֶץ מִצְרָֽיִם׃
(12) Then the LORD said to Moses, “Say to Aaron: Hold out your rod and strike the dust of the earth, and it shall turn to lice throughout the land of Egypt.”
(יג) וַיַּֽעֲשׂוּ־כֵ֗ן וַיֵּט֩ אַהֲרֹ֨ן אֶת־יָד֤וֹ בְמַטֵּ֙הוּ֙ וַיַּךְ֙ אֶת־עֲפַ֣ר הָאָ֔רֶץ וַתְּהִי֙ הַכִּנָּ֔ם בָּאָדָ֖ם וּבַבְּהֵמָ֑ה כָּל־עֲפַ֥ר הָאָ֛רֶץ הָיָ֥ה כִנִּ֖ים בְּכָל־אֶ֥רֶץ מִצְרָֽיִם׃
(13) And they did so. Aaron held out his arm with the rod and struck the dust of the earth, and vermin came upon man and beast; all the dust of the earth turned to lice throughout the land of Egypt.
(ח) וַיֹּ֣אמֶר יְהוָה֮ אֶל־מֹשֶׁ֣ה וְאֶֽל־אַהֲרֹן֒ קְח֤וּ לָכֶם֙ מְלֹ֣א חָפְנֵיכֶ֔ם פִּ֖יחַ כִּבְשָׁ֑ן וּזְרָק֥וֹ מֹשֶׁ֛ה הַשָּׁמַ֖יְמָה לְעֵינֵ֥י פַרְעֹֽה׃ (ט) וְהָיָ֣ה לְאָבָ֔ק עַ֖ל כָּל־אֶ֣רֶץ מִצְרָ֑יִם וְהָיָ֨ה עַל־הָאָדָ֜ם וְעַל־הַבְּהֵמָ֗ה לִשְׁחִ֥ין פֹּרֵ֛חַ אֲבַעְבֻּעֹ֖ת בְּכָל־אֶ֥רֶץ מִצְרָֽיִם׃ (י) וַיִּקְח֞וּ אֶת־פִּ֣יחַ הַכִּבְשָׁ֗ן וַיַּֽעַמְדוּ֙ לִפְנֵ֣י פַרְעֹ֔ה וַיִּזְרֹ֥ק אֹת֛וֹ מֹשֶׁ֖ה הַשָּׁמָ֑יְמָה וַיְהִ֗י שְׁחִין֙ אֲבַעְבֻּעֹ֔ת פֹּרֵ֕חַ בָּאָדָ֖ם וּבַבְּהֵמָֽה׃ (יא) וְלֹֽא־יָכְל֣וּ הַֽחַרְטֻמִּ֗ים לַעֲמֹ֛ד לִפְנֵ֥י מֹשֶׁ֖ה מִפְּנֵ֣י הַשְּׁחִ֑ין כִּֽי־הָיָ֣ה הַשְּׁחִ֔ין בַּֽחֲרְטֻמִּ֖ם וּבְכָל־מִצְרָֽיִם׃
(8) Then the LORD said to Moses and Aaron, “Each of you take handfuls of soot from the kiln, and let Moses throw it toward the sky in the sight of Pharaoh. (9) It shall become a fine dust all over the land of Egypt, and cause an inflammation breaking out in boils on man and beast throughout the land of Egypt.” (10) So they took soot of the kiln and appeared before Pharaoh; Moses threw it toward the sky, and it caused an inflammation breaking out in boils on man and beast. (11) The magicians were unable to confront Moses because of the inflammation, for the inflammation afflicted the magicians as well as all the other Egyptians.
(ד) וזרקו משה. וְכָל דָּבָר הַנִּזְרָק בְּכֹחַ, אֵינוֹ נִזְרָק אֶלָּא בְיַד אַחַת, הֲרֵי נִסִּים הַרְבֵּה – אֶחָד שֶׁהֶחֱזִיק קֻמְצוֹ שֶׁל מֹשֶׁה מְלֹא חָפְנַיִם שֶׁלּוֹ וְשֶׁל אַהֲרֹן, וְאֶחָד שֶׁהָלַךְ הָאָבָק עַל כָּל אֶרֶץ מִצְרַיִם (תנחומא):
(4) וזרקו משה AND LET MOSES THREW IT — Since anything which is thrown with force must be thrown with one hand only, there were here several miracles: one, that Moses’ closed fingers (קמץ) held as much as would fill his two fists and those of Aaron, and another, that this dust spread itself over the entire land of Egypt (Midrash Tanchuma, Vaera 14; Exodus Rabbah 11:8).
