Joshua 4:1-3

And it came to pass, when all the nation were clean passed over the Jordan, that Jehovah spake unto Joshua, saying, Take you twelve men out of the people, out of every tribe a man, and command ye them, saying, Take you hence out of the midst of the Jordan, out of the place where the priests’ feet stood firm, twelve stones, and carry them over with you, and lay them down in the lodging-place, where ye shall lodge this night.
