ציטירנדיקער פּירוש אויף הושע 14:2

A possible weakness with this approach is that it appears to be inconsistent with how Neviim usually deliver their speeches. There is almost always a "but you can change it" part that comes afterwards. Examples of offering the Teshuvah option include Yeshayahu 1:19, Hoshea 14:2-10, and Malachi 3:7-12. In addition, this seems inconsistent with Yonah’s personality. When speaking to sailors in chapter one Yonah either said nothing or went far beyond the scope of the question asked. The “half in half out” style with which he approaches Ninveh is not his motif.

Yonah’s omission of the Teshuvah option is an example of what is stated in Mishlei (19:21) “Rabot Machashavot BeLev Ish VaAtzat Hashem Hi Takum,” “while there are many thoughts in man’s heart, Hashem’s plan will ultimately prevail.” Indeed, Moshe Rabbeinu states (Bemidbar 14:41) “Lamah Zeh Atem Overim Et Pi Hashem VeHi Lo Titzlach,” “why are you violating the word of Hashem, as your efforts will not succeed.” Hoshea (14:2) also teaches “Shuvah Ad Hashem Elokecha, Ki Chashalta BaAvonecha,” “return to God since you have failed in your sins.”
