Article Abstract and Citation Information From the Jerusalem Journal of Archeology:
This article presents a Proto-Canaanite inscription written in ink on a jug. It was unearthed in 2019 at Khirbet al-Ra‘i, located 4 km west of Tel Lachish, in a level dated to the late twelfth or early eleventh century BCE. Only part of the inscription had survived, with five letters indicating the personal name Yrb‘l ( Jerubba‘al). This name also appears in the biblical tradition, more or less in the same era: “[Gideon] from that day was called Yrb‘l” ( Judg. 6:31–32). This inscription, together with similar inscriptions from Beth-Shemesh and Khirbet Qeiyafa, contributes to a better understanding of the distribution of theophoric names with the element ba‘al in the eleventh–tenth centuries BCE in Judah.See also: Jerubba‘al, Proto-Canaanite inscription, Khirbet al-Ra‘i
