We also know quite a lot about the labor force that built the pyramids. The best estimates are that 10,000 men spent 30 years building the Great Pyramid. They lived in good housing at the foot of the pyramid, and when they died, they received honored burials in stone tombs near the pyramid in thanks for their contribution. This information is relatively new, as the first of these worker tombs was only discovered in 1990. They ate well and received the best medical care. And, also unlike slaves, they were well paid. The pyramid builders were recruited from poor communities and worked shifts of three months (including farmers who worked during the months when the Nile flooded their farms), distributing the pharaoh's wealth out to where it was needed most. Each day, 21 cattle and 23 sheep were slaughtered to feed the workers, enough for each man to eat meat at least weekly. Virtually every fact about the workers that archaeology has shown us rules out the use of slave labor on the pyramids.
It wasn't until almost 2,000 years after the Great Pyramid received its capstone that the earliest known record shows evidence of Jews in Egypt, and they were neither Hebrews nor Israelites. They were a garrison of soldiers from the Persian Empire, stationed on Elephantine, an island in the Nile, beginning in about 650 BCE. Their history is known from the Elephantine Papyri discovered in 1903, which are in Aramaic, not Hebrew; and their religious beliefs appear to have been a mixture of Judaism and pagan polytheism. In perhaps the strangest reversal from pop pseudohistory, the papyri include evidence that at least some of the Jewish settlers at Elephantine owned Egyptian slaves.
