For riches are not forever; as Proverbs 23:5. Money and other kinds of wealth may be lost or wasted; it is therefore expedient to have the resources of agriculture, land and herds, to depend upon. Chosen (Proverbs 15:6), translated "riches," is "strength," "abundance," "treasure laid up."
Delitzsch renders, "prosperity;" Septuagint, "A man has not strength and power forever;" Vulgate, Non habebis jugiter potestatem, i.e. "you will not always be able to tend your flocks; infirmity and old age will prevent you."
And doth the crown endure to every generation? The crown or diadem, נֵזֶר (nezer), is the symbol of royal authority, or of the highest dignity of the priesthood (Exodus 29:6; Exodus 39:30). These positions are not secure from generation to generation; much less stable, in fact, than the possession of farms and cattle.
St. Jerome, Sed corona tribuetur in generationem et generationem, where corona is the headship of the family. Septuagint, "Neither doth he transmit it (his strength) from generation to generation."
