Exodus 7:14

וַיַּשְׁלִיכוּ אִישׁ מַטֵּהוּ וַיִּהְיוּ לְתַנִּינִם וַיִּבְלַע מַטֵּֽה־אַהֲרֹן אֶת־מַטֹּתָֽם

For they cast down every man his rod, and they became serpents; but Aaron’s rod swallowed up their rods.

וַיֶּחֱזַק לֵב פַּרְעֹה וְלֹא שָׁמַע אֲלֵהֶם כַּאֲשֶׁר דִּבֶּר יְהוָֽה

And Pharaoh’s heart was hardened, and he hearkened not unto them; as the LORD had spoken.

לֵךְ אֶל־פַּרְעֹה בַּבֹּקֶר הִנֵּה יֹצֵא הַמַּיְמָה וְנִצַּבְתָּ לִקְרָאתוֹ עַל־שְׂפַת הַיְאֹר וְהַמַּטֶּה אֲשֶׁר־נֶהְפַּךְ לְנָחָשׁ תִּקַּח בְּיָדֶֽךָ

Get thee unto Pharaoh in the morning; lo, he goeth out unto the water; and thou shalt stand by the river’s brink to meet him; and the rod which was turned to a serpent shalt thou take in thy hand.

וְאָמַרְתָּ אֵלָיו יְהוָה אֱלֹהֵי הָעִבְרִים שְׁלָחַנִי אֵלֶיךָ לֵאמֹר שַׁלַּח אֶת־עַמִּי וְיַֽעַבְדֻנִי בַּמִּדְבָּר וְהִנֵּה לֹא־שָׁמַעְתָּ עַד־כֹּֽה

And thou shalt say unto him: The LORD, the God of the Hebrews, hath sent me unto thee, saying: Let My people go, that they may serve Me in the wilderness; and, behold, hitherto thou hast not hearkened;
