KJV_Strongs(i)
  2 H2142 And thou shalt remember [H8804]   H1870 all the way H3068 which the LORD H430 thy God H3212 led [H8689]   H705 thee these forty H8141 years H4057 in the wilderness H6031 , to humble [H8763]   H5254 thee, and to prove [H8763]   H3045 thee, to know [H8800]   H3824 what was in thine heart H8104 , whether thou wouldest keep [H8799]   H4687 his commandments, or no.
  3 H6031 And he humbled [H8762]   H7456 thee, and suffered thee to hunger [H8686]   H398 , and fed [H8686]   H4478 thee with manna H3045 , which thou knewest [H8804]   H1 not, neither did thy fathers H3045 know [H8804]   H3045 ; that he might make thee know [H8687]   H120 that man H2421 doth not live [H8799]   H3899 by bread H905 only H4161 , but by every word that proceedeth H6310 out of the mouth H3068 of the LORD H120 doth man H2421 live [H8799]  .
  4 H8071 Thy raiment H1086 waxed not old [H8804]   H7272 upon thee, neither did thy foot H1216 swell [H8804]   H705 , these forty H8141 years.
