to close something off so that nothing can get through it, and so make it inaccessible: from stopping up a well to sealing a message shut
At its root this verb means to close an opening so completely that nothing passes through it any longer. In the narrative books it is a hands-on, physical act: the Philistines fill in Abraham's wells with dirt (Genesis 26), Israel's soldiers block the springs of Moab in wartime (2 Kings 3), and Hezekiah closes the outlet of a spring to reroute its water into Jerusalem (2 Chronicles 32). One detail runs through every case: the word never means to destroy. A stopped well can be dug out again, a blocked spring rerouted, a breached wall filled back in. The point is not ruin but sealing off access.
From there the same picture is applied to things you cannot touch. A sufferer says God has shut off his prayer as if plugging a pipe so it cannot reach him (Lamentations 3); a psalmist speaks of the closed-off inner place where God teaches wisdom (Psalm 51). The physical image is still there underneath, but now the thing being closed is a flow or an inner space rather than a hole in the ground.
At its furthest reach, in Daniel, the word closes off a message. Daniel is told to shut up the vision and shut up the words until the appointed time. The revelation is real and true, but it is kept closed, its meaning held back until the end, when the right readers will finally open it. The same idea of closing off to make something inaccessible carries the word all the way from a plugged well to a sealed prophecy.
Nuances
What it means to shut up the words in the sealing commands of Daniel (8:26; 12:4, 9): whether the verb describes preserving the book physically sealed until the appointed time, or making its meaning cognitively inaccessible until the qualified community can interpret it.
- contestedThe words are shut up because the scroll is sealed as a legal document and stored away, unavailable until the end; the imperative frames the book as preserved from Daniel's day until its own time.; John J. Collins, Daniel (Hermeneia); Louis F. Hartman and Alexander A. Di Lella, The Book of Daniel (Anchor Bible)
- contestedThe verb keeps the meaning of the words shut up, so the message stays obscure to all but the wise, since Daniel 12:8-10 has Daniel himself failing to understand and divides readers into those who will understand and those who will not.; Klaus Koch, Das Buch Daniel; André Lacocque, The Book of Daniel
