Passage
Caph. For the Lord will not cast off for ever.
Caph. For the Lord will not cast off for ever.
Lamentations 3:29 Jod. He shall put his mouth in the dust, if so be there may be hope.
Lamentations 3:30 Jod. He shall give his cheek to him that striketh him, he shall be filled with reproaches.
Lamentations 3:31 Caph. For the Lord will not cast off for ever.
Lamentations 3:32 Caph. For if he hath cast off, he will also have mercy, according to the multitude of his mercies.
Lamentations 3:33 Caph. For he hath not willingly afflicted, nor cast off the children of men.
The verse centers on "caph", "lord", "cast", and "ever". It is saying that the verse draws attention to "caph" and "lord", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 30's "Jod He shall give his cheek to..." into verse 32's "Caph For if he hath cast off...", so "caph" and "lord" belong inside that flow. In Lamentations context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "caph" and "lord" with trust shaped by these words, not by a vague optimism outside the passage.
