Word by word
The verse says
Not needing to be thought well of; not putting on a display; doing no harm; patience; straightness; service to a teacher; cleanliness; steadiness; holding oneself in check —
In plain words
Here the chapter turns, and the turn is abrupt.
A list of twenty qualities begins, and at the end of it Krishna will say: this is knowledge.
Not the inventory just given. These. Knowledge, in this chapter, turns out to be a way of behaving.
Where you've felt this · in family life
Your uncle has never once told anybody about the money he sent his brother's family for eleven years. You found out from a bank letter after he moved house. He was not being modest about it. It had not occurred to him that it was the kind of thing you mention.
Going deeper
Defining knowledge as a list of behaviours is the most surprising thing this chapter does, and it is easy to read past.
Everything up to verse 7 was analysis — components, categories, what belongs where. A reader would expect knowledge to mean grasping that analysis correctly. Instead the word is attached to humility, patience, straightness and the absence of display.
The first item sets the tone. Amānitvam is not thinking well of yourself in a particular way: not needing to be seen.
What that implies is that the analysis cannot be held properly by somebody who needs to be impressive. You can learn the categories while needing to be seen learning them, and this chapter says that person has not understood, however accurately they can recite it.
