Matthew Poole and continuators on Proverbs 27:23

23 Be thou diligent to know the state of thy flocks , and look well to thy herds.

That thou maist preserve and improve what thou hast, and take care that thine expences may not exceed thine incomes. Flocks and Herds are here put for all Riches and possessions, because anciently they were the chief part of a mans Riches.

Heb. set thine heart. Trust not wholly to thy servants, as many do, that they may give up themselves wholly to ease and pleasure, but make use of thine own Eyes and reason for the conduct of thine affairs, lest thou come to ruine, as many have done by this very means.
