Midrash su Genesi 29:6

Whence again dost thou learn this? Know that it is so. Come and see from Moses, for, although he had not yet entered the city, he found maidens coming out before him, as it is said, "Now the priest of Midian had seven daughters; and they came" (Ex. 2:16). And He prospered his way, and he redeemed Israel from Egypt. Whence dost thou know this? Know that it is so. Come and see from Saul, for whilst he had not yet entered the city, he found maidens coming forth before him, as it is said, "As they went up the ascent to the city, they found young maidens going out" (1 Sam. 9:11). And He prospered his way and he acquired the sovereignty. || And whence do we know this? Know thou that it is so. Come and learn from Jacob, for whilst he had not yet entered the city, he found maidens coming forth before him, as it is said, "And, behold, Rachel his daughter cometh" (Gen. 29:6).

R. Yose bar Chanina explained the verse about the exile, “And Jacob said tho them... and they said we are from Charan” (Genesis 29:4) We are running away from the rage of (charono) of the Holy One, blessed be He. “He said to them, 'Do you know Laban the son of Nahor?'…” (Genesis 29:5) Do you know who is going to whiten (lelaven) your iniquities like snow in the future? "And they said, 'we know'" (- as they never lost their hope). "And he said, 'Is there peace with him'; and they said, 'there is peace.'" In the merit of what? "And behold his daughter, Rachel, is coming with the flock." This is [the meaning of] that which is written (Jeremiah 31:15-17), "Rachel weeps for her children... Restrain your eyes form weeping... And there is hope for your future."
