He will not suffer thy foot to be moved; he that keepeth thee will not slumber.
He will not suffer thy foot to be moved; he that keepeth thee will not slumber.
Psalms 121:1 {A Song of degrees.} I lift up mine eyes unto the mountains: whence shall my help come?
Psalms 121:2 My help [cometh] from Jehovah, who made the heavens and the earth.
Psalms 121:3 He will not suffer thy foot to be moved; he that keepeth thee will not slumber.
Psalms 121:4 Behold, he that keepeth Israel will neither slumber nor sleep.
Psalms 121:5 Jehovah is thy keeper, Jehovah is thy shade upon thy right hand;
The verse centers on "suffer", "foot", "moved", "keepeth", "thee", and "slumber". It is saying that the verse draws attention to "suffer" and "foot", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 2's "My help cometh from Jehovah who made..." into verse 4's "Behold he that keepeth Israel will neither...", so "suffer" and "foot" 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 "suffer" and "foot" with trust shaped by these words, not by a vague optimism outside the passage.
