Passage
Mine eyes run down with streams of water, because they keep not thy law.
Mine eyes run down with streams of water, because they keep not thy law.
Psalms 119:134 Deliver me from the oppression of man; and I will keep thy precepts.
Psalms 119:135 Make thy face to shine upon thy servant, and teach me thy statutes.
Psalms 119:136 Mine eyes run down with streams of water, because they keep not thy law.
Psalms 119:137 TZADE. Righteous art thou, Jehovah, and upright are thy judgments.
Psalms 119:138 Thou hast commanded thy testimonies in righteousness and exceeding faithfulness.
The verse centers on "mine", "eyes", "down", "streams", "water", and "keep". It is saying that the verse draws attention to "mine" and "eyes", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 135's "Make thy face to shine upon thy..." into verse 137's "TZADE Righteous art thou Jehovah and upright...", so "mine" and "eyes" 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 "mine" and "eyes" with trust shaped by these words, not by a vague optimism outside the passage.
