cut down. Not same word as 2Ki_6:3. Hebrew. kazab = to cut evenly: i.e. shape or size evenly. Occurs only here and Son_4:2 ("even shorn").
a stick = a helve.
iron did swim = made him see the iron: by causing it to rise to the surface. Elisha's twelfth miracle. See note on 2Ki_2:15. The spiritual application is thus put by John Newton: "Not one concern of ours is small If we belong to Him; To teach us this, the Lord of all Once made the iron to swim".
