24 She maketh fine linen, and selleth it; and delivereth girdles unto the merchant.
When we leave the literal application as to the activities of the virtuous woman we can look at this as being the good works the church does.
Ephesians 2:10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
Fine linen is representative of righteousness.
Revelation 19:8 And to her was granted that she should be arrayed in fine linen, clean and white: for the fine linen is the righteousness of saints.
A girdle was a type of belt or sash worn around the waist or it would be something that encircles a belt. Sometimes it was a garment that gave support and extended below the waist. It symbolized strength as in the following verse that is mentioned.
2Samuel 20:8b ….and upon it a girdle with a sword fastened upon his loins in the sheath thereof; and as he went forth it fell out.
So, here is a symbolic statement of the church’s works in righteousness and her commerce with the world represented by the merchant. Commerce, by the way, as found in the US Constitution, is a word that means more than just economic interaction. It used to mean any kind of interaction with others, not simply where money or goods changed hands.
