a bedspread: a decorative textile spread over a bed or couch
This word names a covering laid across a bed or couch, what English would call a bedspread or coverlet. It is not a floor rug or a wall hanging; it belongs to the world of soft furnishings, the layer of cloth that makes a couch inviting to lie on. The word is built from a root meaning to spread something out, and in one of its two appearances it even pairs with the matching verb, so the phrase reads literally as spreading spreads over a couch.
The word turns up only twice in the Hebrew Bible, both times in Proverbs and both times as a plural, and both pictures are of luxurious, colorful cloth. In one scene a seductress boasts that she has draped her couch with imported spreads of Egyptian linen; in the other a hardworking wife weaves her own out of fine linen and purple. The object is the same in both places; what changes is how each woman came to own it.
Older translations reached for tapestry or carpet, and modern Hebrew has since turned the word into the ordinary term for a rug, which tempts readers to hear carpet here too. Both are later developments. In these two verses the picture is bedding, a cover spread over a place to lie down.
