The fourth plague Arov is not found in the word of Psalms 78. Only seven are described and AROV is not one of them. Does this plague occur or this is another tradition and what is Arov actually?
Let’s examine the verses in Exodus 8, as written:
” וַיֹּ֨אמֶר יְהוָ֜ה אֶל־מֹשֶׁ֗ה הַשְׁכֵּ֤ם בַּבֹּ֙קֶר֙ וְהִתְיַצֵּב֙ לִפְנֵ֣י פַרְעֹ֔ה הִנֵּ֖ה יוֹצֵ֣א הַמָּ֑יְמָה וְאָמַרְתָּ֣ אֵלָ֗יו כֹּ֚ה אָמַ֣ר יְהוָ֔ה שַׁלַּ֥ח עַמִּ֖י וְיַֽעַבְדֻֽנִי׃ כִּ֣י אִם־אֵינְךָ֮ מְשַׁלֵּ֣חַ אֶת־עַמִּי֒ הִנְנִי֩ מַשְׁלִ֨יחַ בְּךָ֜ וּבַעֲבָדֶ֧יךָ וּֽבְעַמְּךָ֛ וּבְבָתֶּ֖יךָ אֶת־הֶעָרֹ֑ב וּמָ֨לְא֜וּ בָּתֵּ֤י מִצְרַ֙יִם֙ אֶת־הֶ֣עָרֹ֔ב וְגַ֥ם הָאֲדָמָ֖ה אֲשֶׁר־הֵ֥ם עָלֶֽיהָ׃ וְהִפְלֵיתִי֩ בַיּ֨וֹם הַה֜וּא אֶת־אֶ֣רֶץ גֹּ֗שֶׁן אֲשֶׁ֤ר עַמִּי֙ עֹמֵ֣ד עָלֶ֔יהָ לְבִלְתִּ֥י הֱיֽוֹת־שָׁ֖ם עָרֹ֑ב לְמַ֣עַן תֵּדַ֔ע כִּ֛י אֲנִ֥י יְהוָ֖ה בְּקֶ֥רֶב הָאָֽרֶץ׃”
“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. 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. 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” (Exodus 8:16-18 JPS translation)
Was it swarms of flies or mixture of scorpions and snakes (Rashi) or animals as lions, tigers, wolves, and bears (Eben Ezra) with pigs (Bechor Shor) or only different kind of wolves (Rashbam)?
The outcome is one –all the land and earth was destroyed because of the Arov.
Have a beautiful day, Eli
