Joshua 4:9; Joshua 4:18

9 Joshua set up the twelve stones that had been in the middle of the Jordan at the spot where the priests who carried the ark of the covenant had stood. And they are there to this day.

18 And the priests came up out of the river carrying the ark of the covenant of the LORD. No sooner had they set their feet on the dry ground than the waters of the Jordan returned to their place and ran at flood stage as before.
