Genesis 35:21

Israel set out again and pitched his tent beyond the Tower of Eder.

And you, watchtower for the flock,
fortified hill of Daughter Zion,
the former rule will come to you,
sovereignty will come to Daughter Jerusalem.

In the same region, shepherds were staying out in the fields and keeping watch at night over their flock.
