Kabbalah zu Bereschit 29:9

When she first appears to Moses (Zohar I:113b), she is called "Angel" (Exodus 3). She did not appear to Jacob as such, except within the figure of Rachel, as it is written, "and Rachel was coming" (Genesis 29:9). This is the form of another (supernal) Rachel, as it is written, "Thus said the Lord, a cry is heard in Ramah...Rachel weeping for her children" (Jeremiah 31:15). "And Rachel was coming"--,"with her flock"--her echelons. "Of her Father"--certainly! And all are counted and accounted for in her hand. "For she was a shepherdess," she leads them, and is accountable for them.
