בראשית רבתי
35:19 – “ותמת רחל” – Rochel Imeinu was thirty six years old when she passed away, and Leah lived until she was forty four years old. At the time that Rochel and Leah got married, they were twenty-two years old – they got married the same year, and they were both were the same age, because they were twins. When Yitzchok Avinu said to Yaakov Avinu in Bereishis 28:2 “וקח לך משם אשה מבנות לבן” – that Yaakov should go get a wife for himself from the daughters of Lavan, Rochel and Leah were not born yet. When Yaakov was on his way to Lavan, he heard that Lavan did not have any daughters, thus he went and hid himself and toiled in Torah in the study house of Eiver. Being that the Tzaddik Yitzchok spoke about the “daughters of Lavan” at the time, his wife became pregnant, and they had daughters at the end of that year. Yaakov Avinu heard that they were born, but too young to marry, thus he did not go to Lavan and instead remained in the Yeshiva of Eiver of fourteen years, until they were able to have children.

29:15 “ויאמר לבן ליעקב הכי אחי אתה ועבדתני חנם” – Rochel Imeinu was five years old when Yaakov arrived at the house of Lavan. After Yaakov worked for Lavan in order to marry Rochel for seven years, she was twelve years at the time, and of childbearing age. (The Ohr Hachaim Hakodosh says this as well).
