'Bondage' in the Bible

And it came to pass during those many days, that the king of Egypt died. And the children of Israel sighed because of the bondage, and cried; and their cry came up to God because of the bondage;

And Moses said to the people, Remember this day, in which ye came out from Egypt, out of the house of bondage; for with a powerful hand hath Jehovah brought you out from this; and nothing leavened shall be eaten.

And it shall be when thy son asketh thee in time to come, saying, What is this? that thou shalt say to him, With a powerful hand Jehovah brought us out from Egypt, out of the house of bondage.

I am Jehovah thy God, who have brought thee out of the land of Egypt, out of the house of bondage.
