Here the model homemaker is a model planner in two ways. She gets up early and assigns tasks to her maids. You cannot assign tasks to your maids if you have no plan what you would like to be accomplished that day. And she considers a field and buys it. She considers how it will fit into the plan of the household.
Careful planning is part of what makes a person wise and productive.
Not to plan is considered foolish and dangerous. This is true even though the Proverbs teach that we do not know what the future may bring. The fact that the Lord is ultimately in control of the future does not mean we shouldn't plan. It means we should commit our work to the Lord and trust him to establish our plans according to his loving purposes. The planning of the apostle Paul.
