2 Kings 6:6  (King James Version)
And the man of God said, Where fell it? And he shewed him the place. And he cut down a stick, and cast it in thither; and the iron did swim.

he cut down
This could have no natural tendency to raise the iron and cause it to swim: it was only a sign, or ceremony, which the prophet chose to employ on the occasion.
2:21 4:41 Exodus 15:25 ; Mark 7:33 Mark 7:34 ; 8:23-25 John 9:6 John 9:7

the iron
This was the real miracle; for the gravity of the metal must otherwise still have kept it at the bottom of the river.
