Passage
This is the day that Jehovah hath made; we will rejoice and be glad in it.
This is the day that Jehovah hath made; we will rejoice and be glad in it.
Psalms 118:22 [The] stone which the builders rejected hath become the head of the corner:
Psalms 118:23 This is of Jehovah; it is wonderful in our eyes.
Psalms 118:24 This is the day that Jehovah hath made; we will rejoice and be glad in it.
Psalms 118:25 Oh save, Jehovah, I beseech thee; Jehovah, I beseech thee, oh send prosperity!
Psalms 118:26 Blessed be he that cometh in the name of Jehovah. We have blessed you out of the house of Jehovah.
The verse centers on "jehovah", "hath", "rejoice", and "glad". It is saying that the verse draws attention to "jehovah" and "hath", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 23's "This is of Jehovah it is wonderful..." into verse 25's "Oh save Jehovah I beseech thee Jehovah...", so "jehovah" and "hath" 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 "jehovah" and "hath" with trust shaped by these words, not by a vague optimism outside the passage.
