Since the discovery of the famous Mesha inscription in 1868, many new Moabite inscriptions have come to light, especially in the last few years. The unprovenanced Moabite Royal Inscription, now on display in the Israel Museum, is the second longest Moabite text, posing several major linguistic, content-related and syntactic problems that have not been solved so far. This inscription might be a modern forgery. But only a test of its authenticity with scientific methods could clear up this question. However, problems with Moabite texts are no clear indicator for forgeries. There are three further texts found in the context of regular excavations at Kh. el-Mude-yine and at el-Ba-lu-? that also have linguistic traits so far unattested in Moabite. These problems will be discussed in detail because they are important for the linguistic classification of Moabite as a peripheral subtype within the broader family of Northwest Semitic languages. As a group, the Moabite texts also shed light on historical problems related to the presence of Israel in the Transjordan.
