And he put his hand into his scrip, and took a stone, and cast it with the sling, and fetching it about struck the Philistine in the forehead: and the stone was fixed in his forehead, and he fell on his face upon the earth.
Rashi
And he fell face downward. He should have fallen backwards since he had been struck on his forehead. But, in order that Dovid should not be troubled to walk [the extra distance] and cut off his head, for Dovid now saved twelve amos and two zeres; for his height was six amos and a zeres, Dovid saved [walking] his entire height back and hs entire height forward.
