  49 H1732 David H7971 put H3027 his hand H3627 in his bag, H3947 took H68 a stone, H7049 and slung H5221 it, and struck H6430 the Philistine H4696 in his forehead; H68 and the stone H2883 sank H4696 into his forehead, H5307 and he fell H6440 on his face H776 to the earth.
  50 H1732 So David H2388 prevailed H4480 over H6430 the Philistine H7050 with a sling H68 and with a stone, H5221 and struck H6430 the Philistine, H4191 and killed H2719 him; but there was no sword H3027 in the hand H1732 of David.
  51 H1732 Then David H7323 ran, H5975 and stood H6430 over the Philistine, H3947 and took H2719 his sword, H8025 and drew H8593 it out of its sheath, H4191 and killed H3772 him, and cut off H7218 his head H6430 therewith. When the Philistines H7200 saw H1368 that their champion H4191 was dead, H5127 they fled.
