Exodus 13:7

Unleavened bread shall be eaten for seven days ; no leavened bread shall be seen with you, and no leaven shall be seen with you in all your territory .

Eat unleavened bread during those seven days; nothing with yeast in it is to be seen among you, nor shall any yeast be seen anywhere within your borders.

Unleavened bread shall be eaten seven days; and there shall no leavened bread be seen with thee, neither shall there be leaven seen with thee in all thy quarters.
