Leviticus 23:5-8 Lev. 23:5-8
5 In the fourteenth day of the first month at even is the LORD'S passover. 6 And on the fifteenth day of the same month is the feast of unleavened bread unto the LORD: seven days ye must eat unleavened bread. 7 In the first day ye shall have an holy convocation: ye shall do no servile work therein. 8 But ye shall offer an offering made by fire unto the LORD seven days: in the seventh day is an holy convocation: ye shall do no servile work therein.
Matthew 26:17-19 Mt. 26:17-19
17 Now the first day of the feast of unleavened bread the disciples came to Jesus, saying unto him, Where wilt thou that we prepare for thee to eat the passover? 18 And he said, Go into the city to such a man, and say unto him, The Master saith, My time is at hand; I will keep the passover at thy house with my disciples. 19 And the disciples did as Jesus had appointed them; and they made ready the passover.
