ASV_Strongs(i)
  16 H2555 If an unrighteous H5707 witness H6965 rise up H376 against any man H6030 to testify H5627 against him of wrong-doing,
  17 H8147 then both H582 the men, H7379 between whom the controversy H5975 is, shall stand H6440 before H3068 Jehovah, H6440 before H3548 the priests H8199 and the judges H3117 that shall be in those days;
  18 H8199 and the judges H3190 shall make diligent H1875 inquisition: H5707 and, behold, if the witness H8267 be a false H5707 witness, H6030 and have testified H8267 falsely H251 against his brother;
  19 H6213 then shall ye do H2161 unto him, as he had thought H6213 to do H251 unto his brother: H1197 so shalt thou put H1197 away H7451 the evil H7130 from the midst of thee.
  20 H7604 And those that remain H8085 shall hear, H3372 and fear, H3254 and shall henceforth H6213 commit H1697 no more any H7451 such evil H7130 in the midst of thee.
  21 H5869 And thine eyes H2347 shall not pity; H5315 life H5315 shall go for life, H5869 eye H5869 for eye, H8127 tooth H8127 for tooth, H3027 hand H3027 for hand, H7272 foot H7272 for foot.
