Musar zu Bereschit 29:6

When Rachel arrived with the צאן, this alludes to the condition of the Jewish people when in exile. The well itself is compared to Sinai; the words כי מן הבאר ההוא ישקו הצאן, "For they would water the sheep from that well," is a reference to the Ten Commandments which issued forth at Mount Sinai. These and numerous other allusions are seen by the various Rabbis as quoted in the Midrash. When Israel is in exile it is referred to as צאן, flock, or sheep, whereas when it is redeemed it is referred to as אדם. On Ezekiel 34,31: ואתן צאני, צאו מרעיתי אדם אתם, "And you My sheep, sheep of My pasture, you are Adam;" Kimchi comments that nowadays you are merely צאן. In the future when you will be redeemed however, you will qualify for the description אדם.
