Mine helpe commeth from the Lord, which hath made the heauen and the earth.
Mine helpe commeth from the Lord, which hath made the heauen and the earth.
Psalms 121:1 A song of degrees. I will lift mine eyes vnto the mountaines, from whence mine helpe shall come.
Psalms 121:2 Mine helpe commeth from the Lord, which hath made the heauen and the earth.
Psalms 121:3 He wil not suffer thy foote to slippe: for he that keepeth thee, will not slumber.
Psalms 121:4 Beholde, he that keepeth Israel, wil neither slumber nor sleepe.
The verse centers on "mine", "helpe", "commeth", "lord", "hath", "heauen", and "earth". It is saying that the verse draws attention to "mine" and "helpe", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "A song of degrees I will lift..." into verse 3's "He wil not suffer thy foote to...", so "mine" and "helpe" 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 "mine" and "helpe" with trust shaped by these words, not by a vague optimism outside the passage.
