hanging strands: the loose hair falling from a head, or the threads left dangling on a weaver's loom
Behind this word sits one simple picture: something that hangs down slack. Hebrew has a verb for hanging low, drooping, and running dry (דלל), and this noun names the thing that hangs.
That is why one short word can cover two scenes that look unrelated at first:
- a woman's hair worn down and falling from her head, praised for its deep color
- the warp threads still fastened to a loom, which the weaver cuts the finished cloth free of
Hezekiah reaches for the second image when he thinks he is dying: his life is being cut away from the loom while the weaving is only half done.
Hebrew already has a plain, general word for hair as a substance (שער), the sort that grows anywhere on a body. This word is narrower and more visual. It names hair as something that hangs, which is exactly why the same word can serve for threads on a loom without any strain at all.
