Study Lenses
The verse centers on "teacheth", "hands", "steel", "broken", "mine", and "arms". It is saying that the verse draws attention to "teacheth" and "hands", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 34's "He maketh my feet like hinds feet..." into verse 36's "Thou hast also given me the shield...", so "teacheth" and "hands" belong inside that flow. In 2 Samuel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "teacheth" and "hands" with trust shaped by these words, not by a vague optimism outside the passage.
