ציטירנדיקער פּירוש אויף קהלת 9:17

From you that He has withheld, not from me. Question: Many prophets prayed for others, such as Elisha (Melachim II 4:33), and [Eliyahu] for the Tzorphis woman. Why did not Yaakov, too, pray for her, although he had children? Furthermore, why was he angry? He should have answered her calmly, as the words of the wise are heard when spoken calmly. The answer is: Yaakov told Rochel that he had prayed for her, but Hashem did not accept the prayer. Rochel said, “If so, you must be wicked.” Thus he was angry with her, as she considered him wicked. He answered her: “I am not like my father. Both of them were childless, and his prayer was accepted because of both their merits. But I am not childless; Hashem has withheld children only from you. With us, only one person’s merit [is relevant]. That is why my prayer is not answered! (Maharshal)
