3:21 Line 3: Conviction. The final line of the tricolon forces the poet from the depths of despair to the surface where there is hope. The final ז recounts the object of the poet’s hope. He calls “this” (זֹאת) to mind (אָשִׁיב אֶל־לִבִּי). The wording refers to the poet’s heart or the seat of his thought and volition. Although Jerusalem’s heart has been in turmoil (1:20; 2:18), which relates to the poet’s own pain, his disposition is changing. The phraseology reminds one of what God states in Deuteronomy.
