'Prison house' in the Bible

And Moses said to the people, Let this day, on which you came out of Egypt, out of your prison-house, be kept for ever in memory; for by the strength of his hand the Lord has taken you out from this place; let no leavened bread be used.

And when your son says to you in time to come, What is the reason for this? say to him, By the strength of his hand the Lord took us out of Egypt, out of the prison-house:

I am the Lord your God who took you out of the land of Egypt, out of the prison-house.
