I've just tried to use the killings dataset to find those who died between the exodus and conquest. The search strings I used was "Label:Killing". I did not find some of the killings that I expected, so I put it into a Visual Filter. Sure enough, the deaths of Nadab & Abihu in Lev 10, and Korah et al in Num 16, are not labelled. Those are rather obvious omissions. Could there be others missing?
