She has slaughtered her beasts; she has mixed her wine; she has also set her table.
Proverbs 9:2

Wisdom has prepared a fine meal including a rich main course, wine, and a fully set table. The implication in this and the previous verse is that she has access to resources, plans well, and executes her plan to completion. She has meat and wine to offer because her prior plans were executed with the same diligence and they bore fruit.
