Passage
Your word I have treasured in my heart, That I may not sin against You.
Your word I have treasured in my heart, That I may not sin against You.
Psalms 119:9 How can a young man keep his way pure? By keeping it according to Your word.
Psalms 119:10 With all my heart I have sought You; Do not let me stray from Your commandments.
Psalms 119:11 Your word I have treasured in my heart, That I may not sin against You.
Psalms 119:12 Blessed are You, O Yahweh; Teach me Your statutes.
Psalms 119:13 With my lips I have recounted All the judgments of Your mouth.
The verse centers on "word", "treasured", "heart", and "against". It is saying that the verse draws attention to "word" and "treasured", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "With all my heart I have sought..." into verse 12's "Blessed are You O Yahweh Teach me...", so "word" and "treasured" 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 "word" and "treasured" with trust shaped by these words, not by a vague optimism outside the passage.
