The Passover lamb was to be sacrificed in the temple on Aviv 14 at “twilight” (Exodus 12:6), or at the “twain of the evening.”  In Hebrew, this is translated, bain ha’arbayim, or “between the evenings.”  The last half of the daylight hours (from about noon to 6:00 p.m.) was further divided into two parts: the minor evening oblation (noon to 3:00 p.m.) and the major evening oblation (3:00 p.m. to 6:00 p.m.).

Thus, “between the evenings” means between these two periods, or about 3:00 p.m.  This was the time midway between the beginning of the sun’s descent into the west (about noon) and its setting (about 6:00 p.m.).  So the Passover lamb was killed at about 3:00 p.m. on Aviv 14.

It was the ninth hour of daylight (about 3:00 p.m.) that Jesus died (Matthew 27:45-50; Mark 15:33-37; Luke 23:44-46).  Thus Jesus died at exactly the same time as Israel’s high priest slaughtered the Passover lamb in the temple.  As such, Jesus was the Passover Lamb for humanity (1 Corinthians 5:7b).
