Exodus 1:11, 14, 16, 22

So they set taskmasters over them to oppress them with hard labor. And the sons of Israel built Pithom and Raamses as storage cities for Pharaoh.

They made their lives bitter with hard labor in mortar, brick, and all kinds of field work. All their labor was harsh and severe.

“When you act as midwives to the Hebrew women and see them on the birthstool, if it is a son, you shall kill him; but if it is a daughter, she shall live.”

Then Pharaoh commanded all his people, saying, “Every son who is born [to the Hebrews] must be thrown into the Nile, but every daughter you shall keep alive.”
