131:1 Yahweh, my heart isn’t haughty, nor my eyes lofty; nor do I concern myself with great matters, or things too wonderful for me.
131:2 Surely I have stilled and quieted my soul, like a weaned child with his mother, like a weaned child is my soul within me.
131:3 Israel, hope in Yahweh, from this time forward and forever more.
The verse centers on "yahweh", "heart", "haughty", "eyes", "lofty", "concern", "myself", and "great". It is saying that the verse draws attention to "yahweh" and "heart", so its meaning should be read from those terms before moving to application.
The local WEB text gives this verse as the immediate unit, so "yahweh" and "heart" carries the first interpretive weight. 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 "yahweh" and "heart" with trust shaped by these words, not by a vague optimism outside the passage.
