Passover and Unleavened Bread

Leviticus 23:5-8

in the first month, on the fourteenth of the month, between the evenings, is the passover to Jehovah;

and on the fifteenth day of this month is the feast of unleavened things to Jehovah; seven days unleavened things ye do eat;

on the first day ye have a holy convocation, ye do no servile work;

and ye have brought near a fire-offering to Jehovah seven days; in the seventh day is a holy convocation; ye do no servile work.'
