leviticus 23:5 In the fourteenth day of the first month at even is the LORD'S passover. - Free Bible Online

      Le 23:5-8. THE PASSOVER.

      5. the Lord's passover--(See Ex 12:2, 14, 18). The institution of the passover was intended to be a perpetual memorial of the circumstances attending the redemption of the Israelites, while it had a typical reference to a greater redemption to be effected for God's spiritual people. On the first and last days of this feast, the people were forbidden to work [Le 23:7, 8]; but while on the Sabbath they were not to do any work, on feast days they were permitted to dress meat--and hence the prohibition is restricted to "no servile work." At the same time, those two days were devoted to "holy convocation"--special seasons of social devotion. In addition to the ordinary sacrifices of every day, there were to be "offerings by fire" on the altar (see Nu 28:19), while unleavened bread was to be eaten in families all the seven days (see 1Co 5:8).
