berit

This is the Hebrew word for covenant used as part of a god's name. In the one verse where it appears this way, the leading men of Shechem run for safety into the temple of El-Berith, which means "God of the Covenant" (Judges 9:46). The god of that sanctuary was known as the god who stood behind sworn agreements, and his name was built out of the ordinary Hebrew word for covenant (בְּרִית). English Bibles either keep the whole name, "El-Berith," or break it apart as "the god Berith."

Earlier in the same story the god of the Shechem sanctuary is called Baal-Berith, "lord of the covenant" (בַּעַל בְּרִית), and it is out of that temple's treasury that Abimelech is handed the silver he uses to hire his gang of thugs (Judges 9:4). Most readers take the two names as two titles for one god at one shrine, since both "God" and "lord" work as ways of naming a divine master.

The name matters beyond the story of Abimelech, because it shows that covenant language was religious vocabulary among Israel's neighbors and not an Israelite invention. A god titled "of the covenant" was a god called on as witness and enforcer when people bound themselves by oath, which is what makes the events of the chapter so pointed: the men who had sworn loyalty to Abimelech, and then broke with him, die in the temple of the very god who guaranteed such oaths. Shechem was also the place the Bible remembers for covenant-making ceremonies, so the town had a long link with sworn pacts, whatever god was named in them.
