Pr 31:16 She considereth a field, and buyeth it; with the fruit of her hands she planteth a vineyard.
She didn't rush out and purchase it because it was what she wanted to do. She considered it or counted the cost first. It wasn't an impulse purchase.
From what we have learned about her, we know she didn't act independently of her husband. But he did trust her to make the purchase without him. I am sure they discussed it first.
Then it says she planted it. The fact that it would require some work after purchasing was part of counting the cost. She again gets right in there and does the work. She doesn't expect others to do all of it for her.
Just as she gave alot of thought to her purchase, so should we. Are we willing to do the work involved after the purchase?
