Passage
Then will I keep thy law continually, for ever and ever;
Then will I keep thy law continually, for ever and ever;
Psalms 119:42 So shall I have wherewith to answer him that reproacheth me; for I confide in thy word.
Psalms 119:43 And take not the word of truth utterly out of my mouth; because I have hoped in thy judgments.
Psalms 119:44 Then will I keep thy law continually, for ever and ever;
Psalms 119:45 And I will walk at liberty, for I have sought thy precepts;
Psalms 119:46 And I will speak of thy testimonies before kings, and will not be ashamed;
The verse centers on "keep", "continually", and "ever". It is saying that the verse draws attention to "keep" and "continually", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 43's "And take not the word of truth..." into verse 45's "And I will walk at liberty for...", so "keep" and "continually" 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 "keep" and "continually" with trust shaped by these words, not by a vague optimism outside the passage.
