CKJV_Strongs(i)
  11 H6030 And it shall be, if it make you answer H7965 of peace, H6605 and open H5971 unto you, then it shall be, that all the people H4672 that is found H4522 in it shall be tributaries H5647 unto you, and they shall serve you.
  12 H7999 And if it will make no peace H6213 with you, but will make H4421 war H6696 against you, then you shall besiege it:

  14 H802 But the women, H2945 and the little ones, H929 and the cattle, H5892 and all that is in the city, H7998 even all the plunder H962 there, shall you take H398 unto yourself; and you shall eat H7998 the plunder H341 of your enemies, H3068 which the Lord H430 your God H5414 has given you.
