Joshua 4:2-9

2Take you twelve men out of the people, out of every tribe a man,

3And command ye them, saying, Take you hence out of the midst of Jordan, out of the place where the priests’ feet stood firm, twelve stones, and ye shall carry them over with you, and leave them in the lodging place, where ye shall lodge this night.

4Then Joshua called the twelve men, whom he had prepared of the children of Israel, out of every tribe a man:

5And Joshua said unto them, Pass over before the ark of Yhwh your God into the midst of Jordan, and take ye up every man of you a stone upon his shoulder, according unto the number of the tribes of the children of Israel:

6That this may be a sign among you, that when your children ask their fathers in time to come, saying, What mean ye by these stones?1

7Then ye shall answer them, That the waters of Jordan were cut off before the ark of the covenant of Yhwh; when it passed over Jordan, the waters of Jordan were cut off: and these stones shall be for a memorial unto the children of Israel for ever.

8And the children of Israel did so as Joshua commanded, and took up twelve stones out of the midst of Jordan, as Yhwh spake unto Joshua, according to the number of the tribes of the children of Israel, and carried them over with them unto the place where they lodged, and laid them down there.

9And Joshua set up twelve stones in the midst of Jordan, in the place where the feet of the priests which bare the ark of the covenant stood: and they are there unto this day.
