Passage
Let thine hand help me; for I have chosen thy precepts.
Let thine hand help me; for I have chosen thy precepts.
Psalms 119:171 My lips shall utter praise, when thou hast taught me thy statutes.
Psalms 119:172 My tongue shall speak of thy word: for all thy commandments are righteousness.
Psalms 119:173 Let thine hand help me; for I have chosen thy precepts.
Psalms 119:174 I have longed for thy salvation, O LORD; and thy law is my delight.
Psalms 119:175 Let my soul live, and it shall praise thee; and let thy judgments help me.
The verse centers on "thine", "hand", "help", "chosen", and "precepts". It is saying that the verse draws attention to "thine" and "hand", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 172's "My tongue shall speak of thy word..." into verse 174's "I have longed for thy salvation O...", so "thine" and "hand" belong inside that flow. In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "thine" and "hand" with trust shaped by these words, not by a vague optimism outside the passage.
