From the Greek Orthodox Migdal Eder (Tower of the Flock) and Fields of Jacob (Genesis 35:21). Beit Sahour.

Migdal Eder or "Tower of the Flock," is where Jacob grazed his sheep on his journey to Hebron after the death of Rachel. "And Israel journeyed, and spread his tent beyond the tower of Edar" (Genesis 35:21). Prophet Micah alluded this place to the coming of Messiah. "And thou, O tower of the flock, the strong hold of the daughter of Zion, unto thee shall it come, even the first dominion; the kingdom shall come to the daughter of Jerusalem" (Micah 4:8). Later, Christian traditions applied Migdal Eder to the watchtowers where shepherds kept watch on their grazing sheep at the time of Christ's birth. "And there were in the same country shepherds abiding in the field, keeping watch over their flock by night" (Luke 2:8).
