Here we see this women buying property. She is putting her money to good use and enabling her to earn more money which helps her to better provide for her family.
The lesson put it like this:
"Her virtue (verse 10) led to
her willing heart (verse 13) which led to
her industry (verse13) which led to
her savings (verse 11) which led to
her investments (verse 16) which led to
her prosperity (verse 25).
Or put another way...
Hard work and a love for others
A heart in pursuit of excellence
God's gracious blessings
