She has invited them to a special banquet (:2) at her house (:1). Here she said, “Come, eat…drink” of what she had prepared for them. In doing so, she also invites them to “leave your simple ways” and “walk in the way of insight.”
But, what Wisdom really offers in these verses is the chance to change as a person – on the inside. “The simple” and “those who have no sense” can change if they want to.
They can choose to “leave their simple ways and live” and start “walking in the way of insight.”
And that changes everything!
