Exodus 8:29

וַיֹּ֣אמֶר מֹשֶׁ֗ה הִנֵּ֨ה אָנֹכִ֜י יוֹצֵ֤א מֵֽעִמָּךְ֙ וְהַעְתַּרְתִּ֣י אֶל־יְהוָ֔ה וְסָ֣ר הֶעָרֹ֗ב מִפַּרְעֹ֛ה מֵעֲבָדָ֥יו וּמֵעַמּ֖וֹ מָחָ֑ר רַ֗ק אַל־יֹסֵ֤ף פַּרְעֹה֙ הָתֵ֔ל לְבִלְתִּי֙ שַׁלַּ֣ח אֶת־הָעָ֔ם לִזְבֹּ֖חַ לַֽיהוָֽה׃

εἶπεν δὲ Μωυσῆς ὅδε ἐγὼ ἐξελεύσομαι ἀπὸ σοῦ καὶ εὔξομαι πρὸς τὸν θεόν, καὶ ἀπελεύσεται ἀπὸ σοῦ ἡ κυνόμυια καὶ ἀπὸ τῶν θεραπόντων σου καὶ τοῦ λαοῦ σου αὔριον· μὴ προσθῇς ἔτι, Φαραώ, ἐξαπατῆσαι τοῦ μὴ ἐξαποστείλαι τὸν λαὸν θῦσαι κυρίῳ.

Y respondió Moisés: He aquí, en saliendo yo de contigo, rogaré á Jehová que las diversas suertes de moscas se vayan de Faraón, y de sus siervos, y de su pueblo mañana; con tal que Faraón no falte más, no dejando ir al pueblo á sacrificar á Jehová.

“As soon as I leave you,” Moses said, “I will pray to the LORD, so that tomorrow the swarms of flies will depart from Pharaoh and his officials and his people. But Pharaoh must not act deceitfully again by refusing to let the people go and sacrifice to the LORD.”
