Shemot 12:16-18

Orthodox Jewish Bible

¹⁶ And in the yom harishon there shall be a mikra kodesh, and in the yom hashevi’i there shall be a mikra kodesh to you; no manner of melachah shall be done in them, except that which every nefesh must eat [i.e., activity necessary for the preparation of food], that only may be done of you.

¹⁷ And ye shall be shomer to safeguard the matzot; for on this very day I brought your tzva’os out of Eretz Mitzrayim; therefore shall ye be shomer over this day in your generations by a chukkat olam.

¹⁸ In the first month, on the fourteenth day of the month at erev, ye shall eat matzot, until the one and twentieth day of the month at erev.
