AKJV_Strongs(i)
  19 H3808 Now there was no H2796 smith H4672 found H3605 throughout all H776 the land H3478 of Israel: H6430 for the Philistines H559 said, H6435 Lest H5680 the Hebrews H6213 make H2719 them swords H176 or H2595 spears:
  20 H3605 But all H3478 the Israelites H3381 went H3381 down H6430 to the Philistines, H3913 to sharpen H376 every man H4282 his share, H855 and his coulter, H7134 and his ax, H4281 and his mattock.
  21 H6477 Yet they had a file H6310 H4281 for the mattocks, H855 and for the coulters, H7969 and for the forks, H7053 H7134 and for the axes, H5324 and to sharpen H1861 the goads.
  22 H1961 So it came H3117 to pass in the day H4421 of battle, H3808 that there was neither H2719 sword H2595 nor spear H4672 found H3027 in the hand H3605 of any H5971 of the people H7586 that were with Saul H3129 and Jonathan: H7586 but with Saul H3129 and with Jonathan H1121 his son H4672 was there found.
  23 H4673 And the garrison H6430 of the Philistines H3318 went H4569 out to the passage H4363 of Michmash.
