Proverbs 9 is split into 3 sections. In this first section, wisdom is poetically personified again, then in the middle section it isn't but then is again in the 3rd section. Just something to keep in mind as we continue....
Read Proverbs 9:1-6.
What are all the things that wisdom has done to prepare the way for her guests?
I personally don't think that each of these things has a meaning...such as we found in the first verse yesterday.
I think that Solomon was just painting a mental picture of the preparation for a big celebration feast for those that choose to accept the invitation.
