וְאָֽמַרְתָּ֙ בַּיּ֣וֹם הַה֔וּא אוֹדְךָ֣ יְהוָ֔ה כִּ֥י אָנַ֖פְתָּ בִּ֑י יָשֹׁ֥ב אַפְּךָ֖ וּֽתְנַחֲמֵֽנִי׃
到那日，你要說：«永恆者啊，我要稱謝你，因為你曾向我發怒，如今你的怒氣已經轉消，你也安慰了我。»
Ibn Ezra
I have already explained [comment on Exodus 2: 2] that in the word “His anger” [Hebrew: appo] [e.g., Genesis 39: 19], a nun is absorbed in the peh. This is evident in the Aramaic cognate. Thus, the word is from the same root as “though you were angry [Hebrew: anafta] with me” [Isaiah 12: 1] and God was angry [Hebrew: hit annaf] with me also.
