  17 H2142 [H8800] Remember H6002 what Amalek H6213 [H8804] did H1870 to thee by the way H3318 [H8800] , when ye had come forth H4714 from Egypt;
  18 H7136 [H8804] How he met H1870 thee by the way H2179 [H8762] , and smote those behind H2826 [H8737] thee, even all that were feeble H310 behind H5889 thee, when thou wast faint H3023 and weary H3373 ; and he feared H430 not God.
