Bullinger notes that “Veiling in mystery (is) seen in the book being fully sealed; the unveiling of mystery in the breaking of them.” (s.v. “Seal (-s)”.)
Hebrew: The corresponding Hebrew word as used in Daniel 12:4, ‘seal’, is #02856 châtham, ‘to close up’; especially ‘to seal’. It is also translated: ‘make an end’, ‘mark’, ‘seal (up)’, ‘stop’. The ‘sealing’ was done by use of the ‘signet’ ring of a person with authority. When Daniel was cast into the lions’ den, Daniel 6:17, the king ‘sealed’, (#2857-Aramaic) the stone with his own ‘signet,’ #05824 ‛izqa’ (Chaldee word) a signet-ring, (as something engraved).
Daniel was instructed to ‘shut up’ the words, (12:4 and 12:9 the words are ‘closed up’), this word is Hebrew #05640, çâtham, sometimes translated ‘to keep secret’.
