Komentarz do Rodzaju 30:22

ויזכר אלהים את רחל AND GOD REMEMBERED RACHEL — He remembered it to her as a merit that she had transmitted the secret signs to her sister and that she was greatly troubled lest she should fall to Esau’s lot if Jacob were to divorce her because she was childless. Indeed, this had entered Esau’s mind when he heard that she was childless (Genesis Rabbah 73:4). The poet refers to this in his Composition (for the First Day of the New Year) “When the Ruddy One (Esau) perceived that she did not travail with child, he hoped to take her for himself and she became terrified”.

Elokim remembered Rochel. He remembered the efforts she made to produce offspring for Yaakov by giving him her maidservant and acquiring the jasmine flowers.

ויזכר אלוקים את רחל, G'd remembered Rachel, etc. We hear from this verse that although Rachel's plight was on G'd's mind, she also needed to pray in order to conceive and give birth. This is why the Torah added: "G'd heard."
