The water coming down from above stood still and rose up in one heap, far away, and the water flowing down to the Yam HaMelach ran out.
וַיַּעַמְדוּ הַמַּיִם הַיֹּרְדִים מִלְמַעְלָה קָמוּ נֵד אֶחָד הַרְחֵק מְאֹד מֵאָדָם הָעִיר אֲשֶׁר מִצַּד צָרְתָן וְהַיֹּרְדִים עַל יָם הָעֲרָבָה יָם הַמֶּלַח תַּמּוּ נִכְרָתוּ׃
יהושע ג:טז
"The water coming down from above stood still; it rose up in one heap very far away, at Adam, the city beside Tzaresan, and the water flowing down to the Sea of the Aravah, the Yam HaMelach, was completely cut off."
Yehoshua 3:16
The kohanim stood on dry ground in the middle of the Yarden, and all Yisrael crossed on dry ground.
וְכׇל יִשְׂרָאֵל עֹבְרִים בֶּחָרָבָה עַד אֲשֶׁר תַּמּוּ כׇּל הַגּוֹי לַעֲבֹר אֶת הַיַּרְדֵּן׃
יהושע ג:יז
"And all Yisrael crossed on dry ground, until the whole nation had finished crossing the Yarden."
Yehoshua 3:17
