זֹ֛את אָשִׁ֥יב אֶל־לִבִּ֖י עַל־כֵּ֥ן אוֹחִֽיל׃ (ס)
Ito ang ibinabalik ko sa aking isipan, kaya't ako'y umaasa pa rin.
Tze'enah Ure'enah
“This” [3:21]. This I have thought, that my troubles are great. I thought again that God cannot cause this and I will hope to God.
Rashi
Still I take this to heart. After my heart told me that my hope from God was gone, I will reply this to my heart, and I will continue to hope. What is it that I will reply to my heart?
