Passage
Blessed is the man, whose strength is in thee, and in whose heart are thy wayes.
Blessed is the man, whose strength is in thee, and in whose heart are thy wayes.
Psalms 84:3 Yea, the sparrowe hath found her an house, and the swallow a nest for her, where she may lay her yong: euen by thine altars, O Lord of hostes, my King and my God.
Psalms 84:4 Blessed are they that dwell in thine house: they will euer praise thee. Selah.
Psalms 84:5 Blessed is the man, whose strength is in thee, and in whose heart are thy wayes.
Psalms 84:6 They going through the vale of Baca, make welles therein: the raine also couereth the pooles.
Psalms 84:7 They goe from strength to strength, till euery one appeare before God in Zion.
The verse centers on "blessed", "whose", "strength", "thee", "heart", and "wayes". It is saying that the verse draws attention to "blessed" and "whose", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 4's "Blessed are they that dwell in thine..." into verse 6's "They going through the vale of Baca...", so "blessed" and "whose" 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 "whose" with trust shaped by these words, not by a vague optimism outside the passage.
