Exodus 1:11-14

So they organized them into work-gangs and put them to hard labor under gang-foremen. They built the storage cities Pithom and Rameses for Pharaoh. But the harder the Egyptians worked them the more children the Israelites had—children everywhere! The Egyptians got so they couldn’t stand the Israelites and treated them worse than ever, crushing them with slave labor. They made them miserable with hard labor—making bricks and mortar and back-breaking work in the fields. They piled on the work, crushing them under the cruel workload.
