Definition: "Br7" in the Bible is an unusual name that refers to a type of fish found only in Jordan, which was originally called "Salamim". It's significant because it was first mentioned in the Old Testament (Gen 38:6) as "a fish of the sea", but the name never fully captured its full meaning. The precise definition varies among scholars, but some might interpret it to refer to a type of fish that is not recognized by other species or was once considered extinct.
