passovers

A form of passover — The one-day Biblical feast or festival (not a holy day) that begins at twilight at the beginning of the fourteenth day of the first month (Abib or Nisan 14), during which the firstborn sons of the Israelites were passed over by God while those of the Egyptians were killed; this feast day is then immediately followed by the seven-day Feast of Unleavened Bread (Nisan 15 to 21; the first and seventh days are holy days or yearly Sabbaths).
