Passage
I haue hid thy promise in mine heart, that I might not sinne against thee.
I haue hid thy promise in mine heart, that I might not sinne against thee.
Psalms 119:9 BETH. Wherewith shall a yong man redresse his waie? in taking heede thereto according to thy woorde.
Psalms 119:10 With my whole heart haue I sought thee: let me not wander from thy commandements.
Psalms 119:11 I haue hid thy promise in mine heart, that I might not sinne against thee.
Psalms 119:12 Blessed art thou, O Lord: teache mee thy statutes.
Psalms 119:13 With my lippes haue I declared all the iudgements of thy mouth.
The verse centers on "haue", "promise", "mine", "heart", "might", "sinne", "against", and "thee". It is saying that the verse draws attention to "haue" and "promise", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "With my whole heart haue I sought..." into verse 12's "Blessed art thou O Lord teache mee...", so "haue" and "promise" 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 "haue" and "promise" with trust shaped by these words, not by a vague optimism outside the passage.
