Kabbalah sur La Genèse 33:2

Because Jacob saw through the Holy Spirit the oppression of the last exile, in the end of days, it is said of him, "Jacob was greatly afraid and distressed" (Beresheet 32:8). As a result, he divided the holy nation in exile into three parts, as it is written: "And he put the handmaids and their children foremost" (Beresheet 33:2). At first in the exile of Edom, "and Leah and her children after, and Rachel and Joseph last of all." Because he saw their eventual poverty and suffering, (he prayed for them): "So that I come back to my father's house in peace" (Beresheet 28:21). (He prayed): "And will give me bread to eat, and clothing to wear" (Ibid.)
