Exodus 8:19

כִּי אִם־אֵינְךָ מְשַׁלֵּחַ אֶת־עַמִּי הִנְנִי מַשְׁלִיחַ בְּךָ וּבַעֲבָדֶיךָ וּֽבְעַמְּךָ וּבְבָתֶּיךָ אֶת־הֶעָרֹב וּמָלְאוּ בָּתֵּי מִצְרַיִם אֶת־הֶעָרֹב וְגַם הָאֲדָמָה אֲשֶׁר־הֵם עָלֶֽיהָ

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.

וְהִפְלֵיתִי בַיּוֹם הַהוּא אֶת־אֶרֶץ גֹּשֶׁן אֲשֶׁר עַמִּי עֹמֵד עָלֶיהָ לְבִלְתִּי הֱיֽוֹת־שָׁם עָרֹב לְמַעַן תֵּדַע כִּי אֲנִי יְהוָה בְּקֶרֶב הָאָֽרֶץ

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.

וַיַּעַשׂ יְהוָה כֵּן וַיָּבֹא עָרֹב כָּבֵד בֵּיתָה פַרְעֹה וּבֵית עֲבָדָיו וּבְכָל־אֶרֶץ מִצְרַיִם תִּשָּׁחֵת הָאָרֶץ מִפְּנֵי הֶעָרֹֽב

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.

וַיִּקְרָא פַרְעֹה אֶל־מֹשֶׁה וּֽלְאַהֲרֹן וַיֹּאמֶר לְכוּ זִבְחוּ לֵֽאלֹהֵיכֶם בָּאָֽרֶץ

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