'Oppress' in the Bible

So the Egyptians assigned taskmasters over the Israelites to oppress them with forced labor. They built Pithom and Rameses as supply cities for Pharaoh.

Now therefore, behold, the cry of the children of Israel is come unto me: and I have also seen the oppression wherewith the Egyptians oppress them.

Thou shalt neither vex a stranger, nor oppress him: for ye were strangers in the land of Egypt.

Also thou shalt not oppress a stranger: for ye know the heart of a stranger, seeing ye were strangers in the land of Egypt.
