Wayyiqra (Leviticus) 23
4 “These are the appointed feasts of יהוה, holy convocations which you are to proclaim in their appointed season. 5 During the first month, on the fourteenth day of the month in the evening, is יהוה Passover. 6 On the fifteenth day of the same month is the Feast of Matzot to יהוה. For seven days you are to eat matzah. 7 On the first day you are to have a holy convocation and you should do no regular work. 8 Instead you are to present an offering made by fire to יהוה for seven days. On the seventh day is a holy convocation, when you are to do no regular work.”
Bemidar (Numbers) 28
16 “On the fourteenth day of the first month is יהוה Passover. 17 On the fifteenth day, there is to be a feast. For seven days, matzot will be eaten. 18 You are to hold a sacred assembly on the first day. You are not to do any laborious work. 19 You are to offer to יהוה burnt offering by fire, two young bulls, one ram and seven male lambs a year old. They are to be flawless. 20 You are to offer their grain offering of fine flour mixed with oil, three tenths of an ephah per bull, two tenths per ram, 21 and one tenth per each of the seven lambs, 22 plus one goat for a sin offering to atone for yourselves. [b] 23 In addition to the morning burnt offering and regular burnt offering, you are to offer these. 24 Just like this you are to offer each day, for seven days, the food to be offered by fire for each day as a pleasing aroma to יהוה, beside the regular burnt offering with its drink offering. 25 On the seventh day, you are to have a sacred assembly, and you are to do no laborious work.
