I'm well aware that there is some skepticism whether e-Tell actually is Bethsaida. After digging at the site, I think I’m supposed to be a true believer that it is!
Well, I’m not a true believer, but I’m pretty much persuaded. They have determined that there was some kind of lagoon system below e-Tell in the 1st century, so it certainly was accessible to the Sea. I wonder if maybe things were already getting difficult, and it perhaps is not a surprise that the New Testament locates Peter, James, and John in Capernaum rather than their home town of Bethsaida. It would be a lot more convenient. In terms of artifacts, there is much to commend e-Tell (especially as compared to the Araj site for which there is not any excavation evidence yet). We and others before us found Herodian lamps, limestone vessels, and coins that all indicate 1st century BCE/CE Jewish habitation. (We found a silver Cleopatra coin while I was working from late 1st century BCE.) In terms of architecture, they were working in one area that was 1st century CE. What’s missing to confirm identification as the Bethsaida? Well, it still doesn’t look like it was much of a polis. Of course there is still lots to excavate, but no sign of Philip’s tomb which I’m kind of imagining to be at least close to the scale of Herod’s at Herodium. There’s the Temple, but it’s hard to see how it was very impressive as anything in the 1st century. No synagogue found yet either. Still, there is still a lot of the site to be investigated.
