Passage
The entrance of thy words giveth light; it giveth understanding unto the simple.
The entrance of thy words giveth light; it giveth understanding unto the simple.
Psalms 119:128 Therefore I esteem all thy precepts concerning all things to be right; and I hate every false way.
Psalms 119:129 Thy testimonies are wonderful: therefore doth my soul keep them.
Psalms 119:130 The entrance of thy words giveth light; it giveth understanding unto the simple.
Psalms 119:131 I opened my mouth, and panted: for I longed for thy commandments.
Psalms 119:132 Look thou upon me, and be merciful unto me, as thou usest to do unto those that love thy name.
The verse centers on "light", "entrance", "words", "giveth", "understanding", and "simple". It is saying that the verse draws attention to "light" and "entrance", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 129's "Thy testimonies are wonderful therefore doth my..." into verse 131's "I opened my mouth and panted for...", so "light" and "entrance" 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 "light" and "entrance" with trust shaped by these words, not by a vague optimism outside the passage.
