This famous line from Proverbs 27:23 (in the old NWT) is used for elders and the organization to justify field service reports. But, what is this verse talking about? Is it about overseers in the congregation? No. In context, there is a good reason for what is stated in this verse. Let us see:
In the RNWT, looking at verses 23-27:
23You should know well the appearance of your flock. Take good care of your sheep,
24 For wealth does not last forever, Nor a crown for all generations.
25 The green grass disappears, new grass appears, And the vegetation of the mountains is gathered in.
26 The young rams provide your clothing, And the male goats provide the price of a field.
27 And there will be enough goat’s milk to feed you, To feed your household, and to sustain your servant girls.
Now, why know well the appearance of your flock? Verse 24 answers. It's all about making a living. Caring for your own livestock can help bring in a decent living. If your flock gets sick and dies, there goes your income.
Context is king.
