John Wesley on Proverbs 31:13

Flax - That she may find employment for her servants. Worketh - She encourages them to work by her example; which was a common practice among princesses in those first ages. Not that it is the duty of kings and queens to use manual operations, but it is the duty of all persons, the greatest not excepted, to improve all their talents, and particularly their time, which is one of the noblest of them, to the service of that God to whom they must give an account, and to the good of that community to which they are related.
