Although the Kebra Nagast and some traditional Ethiopian histories have stated that Gudit (or "Yudit", Judith; another name given her was "Esato", Esther), a 10th-century usurping queen, was Jewish, some scholars consider that it is unlikely that this was the case.
To prove the antiquity and authenticity of their claims, the Beta Israel cite the 9th-century CE testimony of Eldad ha-Dani (the Danite), from a time before the Zagwean dynasty was established.
