SEAL OF MIQNEYAW 8th century B.C.
Most   of   are   familiar   with   the   "wax   seal."   Now-days   it   is   still   sometimes   used   to   give   documents   a   special   stamp.   For   example a graduation certificate or certificate of appreciation are often decorated with it. Archaeologists   have   often   found   seals   on   the   ground   in   Israel.   Sometimes   the   seal   will   mention   who   the   owner   was.   For example,   the   seals   of   Biblical   rulers   like   Ahaz,   Hezekiah   and   queen   Jezebel   have   been   found.   A   seal   bearing   the   name   of   the prophet   Jeremiah’s   secretary,   Baruch,   has   also   been   found.   Seals   could   have   different   shapes;   sometime   they   were   round and   had   images.   These   were   called   cylinder   seals.   Mostly   they   had   the   image   of   a   scarab,   like   the   one   seen   in   our   image.   The little   seal   could   be   part   of   a   ring,   carried   by   the   owner.   Instead   of   writing   a   signature   on   a   document,   a   small   amount   of   soft wax   or   clay   was   put   on   the   document   and   after   the   agreement   the   seal   was   pushed   in   the   wax   or   clay   -   it   was   now   real   and legal.   Sometimes   a   seal   was   used   to   close   a   document,   for   example   a   certificate   or   a   last   will   -   see   Daniel   12:9.   Someone   who was given a royal seal (by the king) could issue royal decrees - see Esther 8:2, 8 and 10. The image shows a seal made of jasper. It's dimensions are only 11,5 x 7,5 x 4,5 millimetres.

The result of the seal print:
On    this    small    stone,    we    see    a    mirror    image    of    text    engraved    in    very    small    ancient    Hebrew    consonants.    It    is    almost unreadable but experts, after an accurate examination, are in agreement that what is written is: lmqnyw ‘bd . yhwh translation: (belonging) to miqneyaw servant of JHWH
It   is   probably   Mikneiah   the   Levite   who   played   the   harp   as   the   “Ark   of   the   covenant”,   in   a   great   moment   of   joy   lead   by   king David, was brought to Jerusalem - see 1 Chronicles 15:18, 21 and 28. Additional note: The   Bible,   besides   the   literal   use   of   seals,   also   mentions   symbolic   seals,   for   example   in   Revelation   5:1(-5).   Opening   or breaking   the   seals   brings   symbolic   plagues   over   the   world.   Also   certain   people,   who   have   received   God’s   approval,   are regarded as 'sealed'. - see Revelation 7:4 and Haggaï 2:23.
