Leviticus 23:5-7

JPS_ASV_Byz(i) 5 In the first month, on the fourteenth day of the month at dusk, 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 shall eat unleavened bread. 7 In the first day ye shall have a holy convocation; ye shall do no manner of servile work.
