As a straightforward interpretation, this verse means exactly what it sounds like. This woman will find her food any place she needs to go to find it. She travels around, trades and seeks foods for her family.
The best modern resource that I can equate this with [personally. though I would love to hear more/other opinions] for a 'modern woman' is couponing. or at least shopping sales for as much of your food as possible. I am not saying that you HAVE to use a coupon or you CANNOT buy something not on sale [pretty sure many would have very little food in their pantry if that were the case], BUT I do believe that planning meals around foods that can be gotten on sale that week is prudent. And if you have the time to get/cut coupons and match them to sales, YEAH! for you. I have some friends who do this very well and save a lot of money on their grocery budget each month. Sadly, I am not one of them. I want to, and I do think it is something I need to learn/take time to accomplish.
BUT, I must also tie in that in this endeavor that I must also still do good to my husband.It may seem contradictory to say this, but if your husband tells you that he does not want you taking your time to devote to coupons and sales adds, then don't. [There are ways to plead your case if you feel it is something that you could handle or have already done in the past, but this post is not about pleading your case.]
To bare my soul, couponing is frustrating for me [I know, really?] and my husband does not like who I am when I am trying to figure it all out [nor do I like who I am], so, I do not use coupons often. I do not acquire or study sales adds. But I also do not buy every ready-made item on the shelf for my family to consume. I can make things. I use the time I would be frustrating over coupons to make the foods from scratch that I would maybe, possibly use a coupon for.
So. for you, for me: remember this heart issue. Am I using my time and our money wisely when acquiring food for my family? Do my pursuits in this continue to do my husband good?
