Israel again commanded to keep passover—Cloud rests upon tabernacle
by day and by night, plus a fire by night—When cloud rested, Israel
camped; when it lifted, they journeyed.
3a fourteenth day of this month
The first month, 'this month', is Nisan or Abib of the Jewish lunar calendar
which occurs during March-April with variation of dates per Gregorian
calendar adjustment. This is
the time of passover and the days of the rites thereof. Passover was when
the firstborn of Israel was passed over as to destruction while the firstborn
of the Egyptians was not. It foreshadowed the Savior's atoning power to
redeem Israel and it was the time of the Savior's own sacrifice to come.
