'Affliction' in the Bible

Thou shalt eat no leavened bread with it; seven days shalt thou eat unleavened bread therewith, even the bread of affliction; for thou camest forth out of the land of Egypt in haste: that thou mayest remember the day when thou camest forth out of the land of Egypt all the days of thy life.

And when we cried unto the LORD God of our fathers, the LORD heard our voice, and looked on our affliction, and our labour, and our oppression:

I have not eaten in mine affliction of it, nor have I put away of it for uncleanness, nor have I given of it for the dead; I have hearkened to the voice of Jehovah my God; I have done according to all that Thou hast commanded me;

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.
