Passage
<FI> Cheth.<Fi> My portion <FI>is<Fi> Jehovah; I have said--to keep Thy words,
<FI> Cheth.<Fi> My portion <FI>is<Fi> Jehovah; I have said--to keep Thy words,
Psalms 119:55 I have remembered in the night Thy name, O Jehovah, And I do keep Thy law.
Psalms 119:56 This hath been to me, That Thy precepts I have kept!
Psalms 119:57 <FI> Cheth.<Fi> My portion <FI>is<Fi> Jehovah; I have said--to keep Thy words,
Psalms 119:58 I appeased Thy face with the whole heart, Favour me according to Thy saying.
Psalms 119:59 I have reckoned my ways, And turn back my feet unto Thy testimonies.
The verse centers on "cheth", "portion", "jehovah", "said--to", "keep", and "words". It is saying that the verse draws attention to "cheth" and "portion", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 56's "This hath been to me That Thy..." into verse 58's "I appeased Thy face with the whole...", so "cheth" and "portion" 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 "cheth" and "portion" with trust shaped by these words, not by a vague optimism outside the passage.
