Passage
The Lord shall preserue thee from all euil: he shall keepe thy soule.
The Lord shall preserue thee from all euil: he shall keepe thy soule.
Psalms 121:5 The Lord is thy keeper: the Lord is thy shadow at thy right hand.
Psalms 121:6 The sunne shall not smite thee by day, nor the moone by night.
Psalms 121:7 The Lord shall preserue thee from all euil: he shall keepe thy soule.
Psalms 121:8 The Lord shall preserue thy going out, and thy comming in from henceforth and for euer.
The verse centers on "lord", "shall", "preserue", "thee", "euil", "keepe", and "soule". It is saying that the verse draws attention to "lord" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "The sunne shall not smite thee by..." into verse 8's "The Lord shall preserue thy going out...", so "lord" and "shall" 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 "lord" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
