Yosua 4:9

4:9 Joshua also set up twelve stones ¹  in the middle of the Jordan in the very place where the priests carrying the ark of the covenant stood. They remain there to this very day.

[4:9]  ¹ tn Here “also” has been supplied in the translation to make it clear (as indicated by v. 20) that these are not the same stones the men took from the river bed.
