Passage
This I will return to my heart; Therefore I will wait in hope.
This I will return to my heart; Therefore I will wait in hope.
Lamentations 3:19 Remember my affliction and my homelessness, the wormwood and gall.
Lamentations 3:20 Surely my soul remembers And is bowed down within me.
Lamentations 3:21 This I will return to my heart; Therefore I will wait in hope.
Lamentations 3:22 The lovingkindnesses of Yahweh indeed never cease, For His compassions never fail.
Lamentations 3:23 They are new every morning; Great is Your faithfulness.
The verse centers on "return", "heart", "therefore", "wait", and "hope". It is saying that the verse draws attention to "return" and "heart", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 20's "Surely my soul remembers And is bowed..." into verse 22's "The lovingkindnesses of Yahweh indeed never cease...", so "return" and "heart" 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 "return" and "heart" with trust shaped by these words, not by a vague optimism outside the passage.
