Numbers 20:15

And the Egyptians evil entreated us, and afflicted us, and laid upon us hard bondage:

Now the sojourning of the children of Israel, who dwelt in Egypt, was four hundred and thirty years.

And they took their cattle, and their goods, which they had gotten in the land of Canaan, and came into Egypt, Jacob, and all his seed with him:

So Jacob went down into Egypt, and died, he, and our fathers,

And he said unto Abram, Know of a surety that thy seed shall be a stranger in a land that is not theirs, and shall serve them; and they shall afflict them four hundred years;

The same dealt subtilly with our kindred, and evil entreated our fathers, so that they cast out their young children, to the end they might not live.

Therefore they did set over them taskmasters to afflict them with their burdens. And they built for Pharaoh treasure cities, Pithom and Raamses. But the more they afflicted them, the more they multiplied and grew. And they were grieved because of the children of Israel. And the Egyptians made the children of Israel to serve with rigour: And they made their lives bitter with hard bondage, in morter, and in brick, and in all manner of service in the field: all their service, wherein they made them serve, was with rigour.

And he said, When ye do the office of a midwife to the Hebrew women, and see them upon the stools; if it be a son, then ye shall kill him: but if it be a daughter, then she shall live.

And Pharaoh charged all his people, saying, Every son that is born ye shall cast into the river, and every daughter ye shall save alive.

And the officers of the children of Israel, which Pharaoh’s taskmasters had set over them, were beaten, and demanded, Wherefore have ye not fulfilled your task in making brick both yesterday and to day, as heretofore?

We remember the fish, which we did eat in Egypt freely; the cucumbers, and the melons, and the leeks, and the onions, and the garlick:

Is it a small thing that thou hast brought us up out of a land that floweth with milk and honey, to kill us in the wilderness, except thou make thyself altogether a prince over us?
