וְאַתָּ֗ה תְּצַוֶּה֙ אֶת־הַכֹּ֣הֲנִ֔ים נֹשְׂאֵ֥י אֲרֽוֹן־הַבְּרִ֖ית לֵאמֹ֑ר כְּבֹאֲכֶ֗ם עַד־קְצֵה֙ מֵ֣י הַיַּרְדֵּ֔ן בַּיַּרְדֵּ֖ן תַּעֲמֹֽדוּ׃ (פ)
Tu, pois, ordenarás aos sacerdotes que levam a arca do pacto, dizendo: Quando chegardes à beira das águas de Jordão, aí parareis.

When you reach the edge of the waters of the Jordan. When you enter within its edge.
Rashi on Joshua
Remain standing in the Jordan. Until all the people cross over to the other side [of the river.]
