I think they’re referencing the ancient Israelites specifically. As the story goes, they were slaves in Egypt. Yahweh sends enough plagues to make the pharaoh release them, and then he gets Moses to guide them to a new home. The historicity of this is doubtful; there absolutely could have been a group of slaves in Egypt that got free and went to what would becone Israel, but there’s no non-religious evidence for much of the rest of it.
Since the story is a kind of foundational tale for both Judaism and Christianity (and possibly other Abrahamic faiths like Islam, but I don’t personally know about them), there’s a strong motivation to look at these incredible buildings and say, “That must have been so much work that it could only have been built by forcing people to work on it. And look, the bible/pentateuch says the Israelites were slaves in that place and time.”
