Yehoshua 4:7-9

Orthodox Jewish Bible

⁷ Then ye shall answer them, That the waters of the Yarden were cut off from before the Aron Brit Hashem; when it passed over the Yarden, the waters of the Yarden were cut off; and these avanim shall be for a zikaron (memorial) unto the Bnei Yisroel ad olam (forever).

⁸ And the Bnei Yisroel did so just as Yehoshua commanded, and took up Shtei Esreh Avanim out of the middle of the Yarden, just as Hashem spoke unto Yehoshua, according to the number of the Shivtei Bnei Yisroel, and carried them over with them unto the malon where they lodged, and laid them down there.

⁹ And Yehoshua set up Shteym Esreh Avanim in the middle of the Yarden, in the place where the feet of the Kohanim bearing the Aron HaBrit stood; and they are there unto this day.
