Rashi on Genesis 31:33/רש"י על בראשית ל״א:ל״ג

1באהל יעקב INTO JACOB’S TENT — This was Rachel’s tent also, for Jacob was constantly with her. For the same reason Scripture says (46:19) “the sons of Rachel Jacob’s wife”, whilst in the case of the other wives it does not state “Jacob’s wife” (Genesis Rabbah 74:9).

2ויבא באהל רחל AND HE CAME INTO RACHEL’S TENT — When he left Leah’s tent he returned again to Rachel’s tent before he searched the tent of the two maid-servants. Why did he feel compelled to do all this? Because he knew full well that she was meddlesome (Genesis Rabbah 74:9).
