'Eat Unleavened Bread' in the Bible

Thou shall eat no leavened bread with it. Seven days thou shall eat unleavened bread with it, even the bread of affliction, for thou came forth out of the land of Egypt in haste, that thou may remember the day when thou came forth

Six days thou shall eat unleavened bread, and on the seventh day shall be a solemn assembly to LORD thy God. Thou shall do no work.
