Adam Clarke on Proverbs 31:15

She riseth also while it is yet night -

4. She is an economist of time; and when the nights are long, and the days short, her family not only spend a part of the evening after sunset in domestic labor, but they all arise before daylight, and prepare the day's food, that they may not have their labor interrupted. To those who are going to the fields, and to the flocks, she gives the food necessary for the day: טרף teref, prey, a term taken from hunting, the object of which was, the supplying their natural wants: hence applied to daily food. See notes on Pro 30:8. And to the women who are to be employed within she gives חק chok, the task - the kind of work they are to do, the materials out of which they are to form it, and the quantity she expects from each. Thus all the servants are settled: their food, work, and tasks appointed. Every thing is done orderly.
