What does the Torah mean when it describes the seven years as "Yamim Achadim" (which seemingly clashes with human nature)?
Rashi: Refer to 29:18:1:1.
Riva #2: After he finished working, it felt that it was a small toil, for he loved her so much. 3
Bechor Shor: This explains why Yakov did not suggest a shorter time. He thought that he was underpaying!
Seforno: Which is why the Torah adds "in his love for her" - because love causes a person to act and to think irrationally.
Pane'ach Raza: However, while working, surely it felt like a long time.
What is the significance of the Torah's constant repetition of the fact that Yakov loved Rachel?
Oznayiom la'Torah: In order to clarify that, when the Torah will mention his hatred of Le'ah, it is only relative to his love of Rachel. 1 In other words, although he loved Le'ah like a man loves his wife, only when compared to his love of Rachel, it is considered hatred. 2
