ויאמר בא אל פרעה. עם אהרן אחיך. ויודיע אותו המכה השנית אם לא ישלח עמי
Background: What are Moshe and Aharon asking for?

(א) וְאַחַ֗ר בָּ֚אוּ מֹשֶׁ֣ה וְאַהֲרֹ֔ן וַיֹּאמְר֖וּ אֶל־פַּרְעֹ֑ה

כֹּֽה־אָמַ֤ר ה' אֱלֹהֵ֣י יִשְׂרָאֵ֔ל שַׁלַּח֙ אֶת־עַמִּ֔י וְיָחֹ֥גּוּ לִ֖י בַּמִּדְבָּֽר׃

(ב) וַיֹּ֣אמֶר פַּרְעֹ֔ה מִ֤י ה' אֲשֶׁ֣ר אֶשְׁמַ֣ע בְּקֹל֔וֹ לְשַׁלַּ֖ח אֶת־יִשְׂרָאֵ֑ל לֹ֤א יָדַ֙עְתִּי֙ אֶת־ה' וְגַ֥ם אֶת־יִשְׂרָאֵ֖ל לֹ֥א אֲשַׁלֵּֽחַ׃

(ג) וַיֹּ֣אמְר֔וּ אֱלֹהֵ֥י הָעִבְרִ֖ים נִקְרָ֣א עָלֵ֑ינוּ נֵ֣לֲכָה נָּ֡א דֶּרֶךְ֩ שְׁלֹ֨שֶׁת יָמִ֜ים בַּמִּדְבָּ֗ר וְנִזְבְּחָה֙ לַֽה' אֱלֹהֵ֔ינוּ פֶּ֨ן־יִפְגָּעֵ֔נוּ בַּדֶּ֖בֶר א֥וֹ בֶחָֽרֶב׃ (ד) וַיֹּ֤אמֶר אֲלֵהֶם֙ מֶ֣לֶךְ מִצְרַ֔יִם לָ֚מָּה מֹשֶׁ֣ה וְאַהֲרֹ֔ן תַּפְרִ֥יעוּ אֶת־הָעָ֖ם מִמַּֽעֲשָׂ֑יו לְכ֖וּ לְסִבְלֹתֵיכֶֽם׃

(1) And afterward Moses and Aaron came, and said to Pharaoh: ‘Thus says the LORD, the God of Israel: Let My people go, that they may hold a feast unto Me in the wilderness.’ (2) And Pharaoh said: ‘Who is the LORD, that I should hearken unto His voice to let Israel go? I know not the LORD, and moreover I will not let Israel go.’ (3) And they said: ‘The God of the Hebrews hath met with us. Let us go, we pray thee, three days’journey into the wilderness, and sacrifice unto the LORD our God; lest He fall upon us with pestilence, or with the sword. (4) And the king of Egypt said unto them: ‘Wherefore do ye, Moses and Aaron, cause the people to break loose from their work? get you unto your burdens.’

In Chavrutot: Dialogue between Moshe and Paroah:

(טז) וַיֹּ֨אמֶר ה' אֶל־מֹשֶׁ֗ה הַשְׁכֵּ֤ם בַּבֹּ֙קֶר֙ וְהִתְיַצֵּב֙ לִפְנֵ֣י פַרְעֹ֔ה הִנֵּ֖ה יוֹצֵ֣א הַמָּ֑יְמָה וְאָמַרְתָּ֣ אֵלָ֗יו כֹּ֚ה אָמַ֣ר ה' שַׁלַּ֥ח עַמִּ֖י וְיַֽעַבְדֻֽנִי׃ (יז) כִּ֣י אִם־אֵינְךָ֮ מְשַׁלֵּ֣חַ אֶת־עַמִּי֒ הִנְנִי֩ מַשְׁלִ֨יחַ בְּךָ֜ וּבַעֲבָדֶ֧יךָ וּֽבְעַמְּךָ֛ וּבְבָתֶּ֖יךָ אֶת־הֶעָרֹ֑ב וּמָ֨לְא֜וּ בָּתֵּ֤י מִצְרַ֙יִם֙ אֶת־הֶ֣עָרֹ֔ב וְגַ֥ם הָאֲדָמָ֖ה אֲשֶׁר־הֵ֥ם עָלֶֽיהָ׃ (יח) וְהִפְלֵיתִי֩ בַיּ֨וֹם הַה֜וּא אֶת־אֶ֣רֶץ גֹּ֗שֶׁן אֲשֶׁ֤ר עַמִּי֙ עֹמֵ֣ד עָלֶ֔יהָ לְבִלְתִּ֥י הֱיֽוֹת־שָׁ֖ם עָרֹ֑ב לְמַ֣עַן תֵּדַ֔ע כִּ֛י אֲנִ֥י ה' בְּקֶ֥רֶב הָאָֽרֶץ׃ (יט) וְשַׂמְתִּ֣י פְדֻ֔ת בֵּ֥ין עַמִּ֖י וּבֵ֣ין עַמֶּ֑ךָ לְמָחָ֥ר יִהְיֶ֖ה הָאֹ֥ת הַזֶּֽה׃ (כ) וַיַּ֤עַשׂ ה' כֵּ֔ן וַיָּבֹא֙ עָרֹ֣ב כָּבֵ֔ד בֵּ֥יתָה פַרְעֹ֖ה וּבֵ֣ית עֲבָדָ֑יו וּבְכָל־אֶ֧רֶץ מִצְרַ֛יִם תִּשָּׁחֵ֥ת הָאָ֖רֶץ מִפְּנֵ֥י הֶעָרֹֽב׃

(16) And the LORD said unto Moses: ‘Rise up early in the morning, and stand before Pharaoh; lo, he cometh forth to the water; and say unto him: Thus saith the LORD: Let My people go, that they may serve Me. (17) Else, if thou wilt not let My people go, behold, I will send swarms of flies upon thee, and upon thy servants, and upon thy people, and into thy houses; and the houses of the Egyptians shall be full of swarms of flies, and also the ground whereon they are. (18) And I will set apart in that day the land of Goshen, in which My people dwell, that no swarms of flies shall be there; to the end that thou mayest know that I am the LORD in the midst of the earth. (19) And I will put a division between My people and thy people—by to-morrow shall this sign be.’ (20) And the LORD did so; and there came grievous swarms of flies into the house of Pharaoh, and into his servants’houses; and in all the land of Egypt the land was ruined by reason of the swarms of flies.

(21) And Pharaoh called for Moses and for Aaron, and said: ‘Go ye, sacrifice to your God in the land.’

(22) And Moses said: ‘It is not meet so to do; for we shall sacrifice the abomination of the Egyptians to the LORD our God; lo, if we sacrifice the abomination of the Egyptians before their eyes, will they not stone us?

(23) We will go three days’journey into the wilderness, and sacrifice to the LORD our God, as He shall command us.’

(24) And Pharaoh said: ‘I will let you go, that ye may sacrifice to the LORD your God in the wilderness; only ye shall not go very far away; entreat for me.’

(25) And Moses said: ‘Behold, I go out from thee, and I will entreat the LORD that the swarms of flies may depart from Pharaoh, from his servants, and from his people, tomorrow; only let not Pharaoh deal deceitfully any more in not letting the people go to sacrifice to the LORD.’ (26) And Moses went out from Pharaoh, and entreated the LORD. (27) And the LORD did according to the word of Moses; and He removed the swarms of flies from Pharaoh, from his servants, and from his people; there remained not one. (28) And Pharaoh hardened his heart this time also, and he did not let the people go.
