Be sure you know the condition of your flocks, give careful attention to your herds;
For riches do not endure forever, and a crown is not secure for all generations.
When the hay is removed and new growth appears and the grass from the hills is gathered in,
the lambs will provide you with clothing, and the goats with the price of a field.
You will have plenty of goats’ milk to feed your family and to nourish your female servants.
Proverbs 27:23-27 NIV
