ציטירנדיקער פּירוש אויף יונה 4:10

son of — bin with a ḥiriq is equivalent to ben with a tsere. See also rish (Prov. 28:19) and resh (Prov. 13:18), bin Nun (Ex. 33:11 et al.), bin layla (Jon. 4:10), bin hakot (Deut. 25:2).

In the phrase deserves flogging the Hebrew word bin is vocalized with a ḥiriq , as it is in the phrases “the son of Nun” [Joshua 1: 1], and “the son of Yaqeh” [Proverbs 30: 1]. It is used in the sense of “a base man” [I Samuel 25: 17] and, similarly, “it was a creature of a night” [Jonah 4: 10]. The reason he deserves to be flogged must be, in my opinion, that he struck his companion.

Hashem tells Yonah, “Arah Chaseta Al HaKikayon Asher Lo Amaleta Bo VeLo Gidaleto… Ve’Ani Lo Achus At Nineveh Ha’Ir HaGedolah Asher Yesh Bah Har’beih MiShetayim Esireih Ribo Adam,” “You took pity on the Kikayon for which you did not labor, nor did you make it grow... and I— shall I not take pity upon Nineveh the great city, in which there are more than a hundred and twenty thousand persons?” (Yonah 4:10-11). The analogy, though, appears to be entirely inapt. Hashem intrinsically cares about Nineveh, while Yonah does not care about the Kikayon per se, but rather for what it provides and for what it represents.
