Passage
Confide ye in Jehovah for ever; for in Jah, Jehovah, is the rock of ages.
Confide ye in Jehovah for ever; for in Jah, Jehovah, is the rock of ages.
Isaiah 26:2 Open ye the gates, and the righteous nation which keepeth faithfulness shall enter in.
Isaiah 26:3 Thou wilt keep in perfect peace the mind stayed [on thee], for he confideth in thee.
Isaiah 26:4 Confide ye in Jehovah for ever; for in Jah, Jehovah, is the rock of ages.
Isaiah 26:5 For he bringeth down them that dwell on high; the lofty city, he layeth it low, he layeth it low to the ground, he bringeth it even to the dust.
Isaiah 26:6 The foot shall tread it down, the feet of the afflicted, the steps of the poor.
The verse centers on "confide", "jehovah", "ever", "rock", and "ages". It is saying that the verse draws attention to "confide" and "jehovah", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "Thou wilt keep in perfect peace the..." into verse 5's "For he bringeth down them that dwell...", so "confide" and "jehovah" belong inside that flow. In Isaiah context, the local focus is the Holy One of Israel, judgment and restoration, the servant of the LORD, and Zion's hope.
A plain takeaway is to answer the verse's own emphasis on "confide" and "jehovah" with trust shaped by these words, not by a vague optimism outside the passage.
