Passage
Blessed art thou, O Jehovah: Teach me thy statutes.
Blessed art thou, O Jehovah: Teach me thy statutes.
Psalms 119:10 With my whole heart have I sought thee: Oh let me not wander from thy commandments.
Psalms 119:11 Thy word have I laid up in my heart, That I might not sin against thee.
Psalms 119:12 Blessed art thou, O Jehovah: Teach me thy statutes.
Psalms 119:13 With my lips have I declared All the ordinances of thy mouth.
Psalms 119:14 I have rejoiced in the way of thy testimonies, As much as in all riches.
The verse centers on "blessed", "thou", "jehovah", "teach", and "statutes". It is saying that the verse draws attention to "blessed" and "thou", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 11's "Thy word have I laid up in..." into verse 13's "With my lips have I declared All...", so "blessed" and "thou" 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 "blessed" and "thou" with trust shaped by these words, not by a vague optimism outside the passage.
