Pesach
Pesach [pey-sahkh] or Passover is the first of the seven feasts of the LORD that GOD proclaimed holy and ordained the children of Israel to observe forever (Leviticus 23:4-5; Numbers 9:2-3; Exodus 12:14). It is a festival of deliverance from physical and spiritual bondage.
Pesach is a one-day feast, immediately followed by the seven-day Feast of Unleavened Bread. The two feasts are typically blended together and simply called Pesach (Passover). GOD ordained that Pesach be observed each year on the 14th day of Nisan (March/April). So awesome was GOD’s deliverance that HE altered Israel’s religious calendar to reflect the month of Nisan as the new beginning (first month) of their religious year.
