Passage
Teach me good discernment and knowledge, For I believe in Your commandments.
Teach me good discernment and knowledge, For I believe in Your commandments.
Psalms 119:64 The earth, O Yahweh, is full of Your lovingkindness; Teach me Your statutes.
Psalms 119:65 You have dealt well with Your slave, O Yahweh, according to Your word.
Psalms 119:66 Teach me good discernment and knowledge, For I believe in Your commandments.
Psalms 119:67 Before I was afflicted I went astray, But now I keep Your word.
Psalms 119:68 You are good and do good; Teach me Your statutes.
The verse centers on "teach", "good", "discernment", "knowledge", "believe", and "commandments". It is saying that the verse draws attention to "teach" and "good", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 65's "You have dealt well with Your slave..." into verse 67's "Before I was afflicted I went astray...", so "teach" and "good" 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 "teach" and "good" with trust shaped by these words, not by a vague optimism outside the passage.
