Joshua 3:12-13

12Now then, 1take for yourselves twelve men from the tribes of Israel, one man for each tribe. 13It shall come about when the soles of the feet of the priests who carry the ark of the Lord, the Lord of all the earth, rest in the waters of the Jordan, the waters of the Jordan will be cut off, and the waters which are 2flowing down from above 3will 4stand in one heap.”
