Mikvah

Hebron plays a central role in many biblical stories. It was the prominent city in the Judean highlands, with large fortifications in the Early Bronze, Middle Bronze, and Iron Ages. During the Second Temple period, Hebron was occupied by the Idumeans. Recent archaeological excavations have uncovered large mikvaot (ritual baths), indicating that the inhabitants embraced Judaism.
