Tanakh para sa Levitico 23:9

When you bring a meal-offering of first grains to Adonoy, of newly ripened crops, roasted over fire, ground [full and moist] kernels, you shall bring your first grain meal-offering.

Take heed of the month of spring, when you will celebrate Pesach for Adonoy your God; for in the month of spring Adonoy, your God, took you out from Egypt at night.

For six days you shall eat matzos, and on the seventh day, is one of withdrawal for the sake of Adonoy, your God, do not do work.
