AKJV_Strongs(i)
  7 H4428 When the king H894 of Babylon’s H2428 army H3898 fought H5921 against H3389 Jerusalem, H5921 and against H3605 all H5892 the cities H3063 of Judah H3498 that were left, H413 against H3923 Lachish, H413 and against H5825 Azekah: H2007 for these H4013 defended H5892 cities H7604 remained H5892 of the cities H3063 of Judah.
  8 H1697 This is the word H1961 that came H3414 to Jeremiah H3068 from the LORD, H310 after H4428 that the king H6667 Zedekiah H3772 had made H1285 a covenant H3605 with all H5971 the people H834 which H3389 were at Jerusalem, H7121 to proclaim H1865 liberty to them;
  9 H376 That every man H5650 should let his manservant, H376 and every man H8198 his maidservant, H5680 being an Hebrew H5680 or an Hebrewess, H7971 go H2670 free; H1115 that none H5647 should serve H3064 himself of them, to wit, of a Jew H251 his brother.
  10 H3605 Now when all H8269 the princes, H3605 and all H5971 the people, H834 which H935 had entered H1285 into the covenant, H8085 heard H376 that every H376 one H5650 should let his manservant, H376 and every H376 one H8198 his maidservant, H7971 go H2670 free, H1115 that none H5647 should serve H5750 themselves of them any more, H8085 then they obeyed, H7971 and let them go.
  11 H310 But afterward H3651 H7725 they turned, H5650 and caused the servants H8198 and the handmaids, H834 whom H7971 they had let go H2670 free, H7725 to return, H3533 and brought H3533 them into subjection H5650 for servants H8198 and for handmaids.
