Passage
I cried with my whole heart; hear me, O LORD: I will keep thy statutes.
I cried with my whole heart; hear me, O LORD: I will keep thy statutes.
Psalms 119:143 Trouble and anguish have taken hold on me: yet thy commandments are my delights.
Psalms 119:144 The righteousness of thy testimonies is everlasting: give me understanding, and I shall live.
Psalms 119:145 I cried with my whole heart; hear me, O LORD: I will keep thy statutes.
Psalms 119:146 I cried unto thee; save me, and I shall keep thy testimonies.
Psalms 119:147 I prevented the dawning of the morning, and cried: I hoped in thy word.
The verse centers on "cried", "whole", "heart", "lord", "keep", and "statutes". It is saying that the verse draws attention to "cried" and "whole", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 144's "The righteousness of thy testimonies is everlasting..." into verse 146's "I cried unto thee save me and...", so "cried" and "whole" 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 "cried" and "whole" with trust shaped by these words, not by a vague optimism outside the passage.
