We just passed Easter and Passover, and the pompous Cecil B Demille version of The Ten Commandments was on TV this past weekend. The kids had never seen it, so we put it on the DRV; at four and a half hours, it was too much for a single sitting, and there are too many commercials. We just finished.
Our kids are well trained geeks. My 10 year old declared, "Moses is at least a 13th level cleric". My daughter said he was a water bender like Ang the Avatar. When Ramses decided to plunge his chariots into the canyon of water, my wife is like, "Where is Admiral Ackbar when you need him?" Then my son started conjecturing whether the fiery pillar was a flame strike spell or a wall of fire.
Assuming that the plague of hail is a suped-up Weather Control spell, I'd actually put Moses at 16th level in AD&D terms - Weather Control is a 7th level cleric spell. I think old Gygax must have liked that Cecil B Demille movie quite a bit. You could argue there was Sticks to Snakes, Insect Plagues, Flame Strikes, Part Water, Control Weather, and even a bit of Commune in it.
As for the whole angel of death bit, regular clerics have got nothing.
