'Affliction' in the Bible

You shall not eat leavened bread with it; instead, for seven days you shall eat the Passover with unleavened bread, the bread of affliction (for you left the land of Egypt in haste); [do this] so that all the days of your life you may remember [thoughtfully] the day when you came out of the land of Egypt.

Then we cried out to the Lord, the God of our fathers for help, and He heard our voice and saw our suffering and our labor and our [cruel] oppression;

Also the Lord will bring on you every sickness and every plague which is not written in this book of this law, until you are destroyed.
