The Bible
Joshua 4
Joshua places twelve stones to commemorate the crossing of the Jordan—Joshua is magnified before the children of Israel as they cross the Jordan—After the priests bearing the ark pass over, the river returns to its course.
2Take you twelve men out of the people, out of every tribe a man,
15And the Lord spake unto Joshua, saying,
16Command the priests that bear the ark of the testimony, that they come up out of Jordan.
17Joshua therefore commanded the priests, saying, Come ye up out of Jordan.
20And those twelve stones, which they took out of Jordan, did Joshua pitch in Gilgal.
22Then ye shall let your children know, saying, Israel came over this Jordan on dry land.
