Exodus 1:11, 14, 16, 22

So the Egyptians made the Israelites their slaves. They appointed brutal slave drivers over them, hoping to wear them down with crushing labor. They forced them to build the cities of Pithom and Rameses as supply centers for the king.

They made their lives bitter, forcing them to mix mortar and make bricks and do all the work in the fields. They were ruthless in all their demands.

“When you help the Hebrew women as they give birth, watch as they deliver. If the baby is a boy, kill him; if it is a girl, let her live.”

Then Pharaoh gave this order to all his people: “Throw every newborn Hebrew boy into the Nile River. But you may let the girls live.”
