Why was “changing the staff” the first sign in all three scenarios?
What were Moshe and the people supposed to learn from turning the stick into a snake?
Were these three signs performed in front of Paroh?
What was the תנין and what did it symbolize?
(ב) וַיֹּ֧אמֶר אֵלָ֛יו יְהֹוָ֖ה (מזה) [מַה־זֶּ֣ה] בְיָדֶ֑ךָ וַיֹּ֖אמֶר מַטֶּֽה׃ (ג) וַיֹּ֙אמֶר֙ הַשְׁלִיכֵ֣הוּ אַ֔רְצָה וַיַּשְׁלִכֵ֥הוּ אַ֖רְצָה וַיְהִ֣י לְנָחָ֑שׁ וַיָּ֥נׇס מֹשֶׁ֖ה מִפָּנָֽיו׃
(2) The LORD said to him, “What is that in your hand?” And he replied, “A rod.” (3) He said, “Cast it on the ground.” He cast it on the ground and it became a snake; and Moses recoiled from it.
(כא) וַיֹּ֣אמֶר יְהֹוָה֮ אֶל־מֹשֶׁה֒ בְּלֶכְתְּךָ֙ לָשׁ֣וּב מִצְרַ֔יְמָה רְאֵ֗ה כׇּל־הַמֹּֽפְתִים֙ אֲשֶׁר־שַׂ֣מְתִּי בְיָדֶ֔ךָ וַעֲשִׂיתָ֖ם לִפְנֵ֣י פַרְעֹ֑ה וַאֲנִי֙ אֲחַזֵּ֣ק אֶת־לִבּ֔וֹ וְלֹ֥א יְשַׁלַּ֖ח אֶת־הָעָֽם׃
(21) And the LORD said to Moses, “When you return to Egypt, see that you perform before Pharaoh all the marvels that I have put within your power. I, however, will stiffen his heart so that he will not let the people go.
(ל) וַיְדַבֵּ֣ר אַהֲרֹ֔ן אֵ֚ת כׇּל־הַדְּבָרִ֔ים אֲשֶׁר־דִּבֶּ֥ר יְהֹוָ֖ה אֶל־מֹשֶׁ֑ה וַיַּ֥עַשׂ הָאֹתֹ֖ת לְעֵינֵ֥י הָעָֽם׃
(30) Aaron repeated all the words that the LORD had spoken to Moses, and he performed the signs in the sight of the people,
(ח) וַיֹּ֣אמֶר יְהֹוָ֔ה אֶל־מֹשֶׁ֥ה וְאֶֽל־אַהֲרֹ֖ן לֵאמֹֽר׃ (ט) כִּי֩ יְדַבֵּ֨ר אֲלֵכֶ֤ם פַּרְעֹה֙ לֵאמֹ֔ר תְּנ֥וּ לָכֶ֖ם מוֹפֵ֑ת וְאָמַרְתָּ֣ אֶֽל־אַהֲרֹ֗ן קַ֧ח אֶֽת־מַטְּךָ֛ וְהַשְׁלֵ֥ךְ לִפְנֵֽי־פַרְעֹ֖ה יְהִ֥י לְתַנִּֽין׃ (י) וַיָּבֹ֨א מֹשֶׁ֤ה וְאַהֲרֹן֙ אֶל־פַּרְעֹ֔ה וַיַּ֣עֲשׂוּ כֵ֔ן כַּאֲשֶׁ֖ר צִוָּ֣ה יְהֹוָ֑ה וַיַּשְׁלֵ֨ךְ אַהֲרֹ֜ן אֶת־מַטֵּ֗הוּ לִפְנֵ֥י פַרְעֹ֛ה וְלִפְנֵ֥י עֲבָדָ֖יו וַיְהִ֥י לְתַנִּֽין׃ (יא) וַיִּקְרָא֙ גַּם־פַּרְעֹ֔ה לַֽחֲכָמִ֖ים וְלַֽמְכַשְּׁפִ֑ים וַיַּֽעֲשׂ֨וּ גַם־הֵ֜ם חַרְטֻמֵּ֥י מִצְרַ֛יִם בְּלַהֲטֵיהֶ֖ם כֵּֽן׃ (יב) וַיַּשְׁלִ֙יכוּ֙ אִ֣ישׁ מַטֵּ֔הוּ וַיִּהְי֖וּ לְתַנִּינִ֑ם וַיִּבְלַ֥ע מַטֵּֽה־אַהֲרֹ֖ן אֶת־מַטֹּתָֽם׃ (יג) וַיֶּחֱזַק֙ לֵ֣ב פַּרְעֹ֔ה וְלֹ֥א שָׁמַ֖ע אֲלֵהֶ֑ם כַּאֲשֶׁ֖ר דִּבֶּ֥ר יְהֹוָֽה׃ {ס}
(8) The LORD said to Moses and Aaron, (9) “When Pharaoh speaks to you and says, ‘Produce your marvel,’ you shall say to Aaron, ‘Take your rod and cast it down before Pharaoh.’ It shall turn into a serpent.” (10) So Moses and Aaron came before Pharaoh and did just as the LORD had commanded: Aaron cast down his rod in the presence of Pharaoh and his courtiers, and it turned into a serpent. (11) Then Pharaoh, for his part, summoned the wise men and the sorcerers; and the Egyptian magicians, in turn, did the same with their spells; (12) each cast down his rod, and they turned into serpents. But Aaron’s rod swallowed their rods. (13) Yet Pharaoh’s heart stiffened and he did not heed them, as the LORD had said.
