Hezekiah's Textile Metaphors

Hezekiah wrote this about when he was sick and dying (he got better):

"'Like a shepherd's tent my dwelling is pulled up and removed from me;
As a weaver I rolled up my life.
He [the Lord] cuts me off from the loom;
From day until night You make an end of me.'"

Isaiah 38:12 NASB

I think it's beautiful how he uses the imagery of textiles as a metaphor for his physical and spiritual condition.

I am also impressed with how much a part of everyday life textile manufacture and sheep-raising appear in the book of Isaiah.

The prophet refers to an enemy commander turning up to have a parlay with the king's representatives (and to deliver some choice threats): the man "stood by the conduit of the upper pool on the highway of the fuller's field." Is 36:2b NASB

If there are any fuller's fields around here as landmarks, I don't know about them.

Oh, the sheep-raising verse I promised:

"For thus says the Lord to me,
'As the lion or the young lion growls over his prey,
Against which a band of shpherds is called out,
And he will not be terrified at their voice nor disturbed at their noise,'"

Isaiah 31:4 NASB

I get that metaphor but not the way people back in the day, who actually kept sheep with lions around, would have gotten it.
