Exodus 10:13

ורוח הקדים THE EAST WIND — It was an east wind that brought the locusts because that came (blew) from the direction opposite to it (to Egypt), since Egypt was in the south-west, relative to Palestine, as it is explained in another place (Numbers 34:3).

וַיֵּ֨ט מֹשֶׁ֣ה אֶת־מַטֵּ֘הוּ֮ עַל־אֶ֣רֶץ מִצְרַ֒יִם֒ וַֽיהֹוָ֗ה נִהַ֤ג רֽוּחַ־קָדִים֙ בָּאָ֔רֶץ כׇּל־הַיּ֥וֹם הַה֖וּא וְכׇל־הַלָּ֑יְלָה הַבֹּ֣קֶר הָיָ֔ה וְר֙וּחַ֙ הַקָּדִ֔ים נָשָׂ֖א אֶת־הָאַרְבֶּֽה׃

So Moshe stretched out his rod over the land of Miżrayim, and the Lord brought an east wind upon the land all that day, and all that night; and when it was morning, the east wind brought the locusts.
