The Passover lamb was to be sacrificed in the temple on Aviv 14 (Preparation Day) at “twilight” (Exodus 12:6), or at the “twain of the evenings.”  In Hebrew, the literal translation of “twilight” is beyn ha’arbayim, or “between the evenings” (see Exodus 12:6 in Young’s Literal Translation).

The last half of the daylight hours (from about noon to 6:00 p.m.) were further divided into two parts.  These were 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.  During Spring-time, this is 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 approximately 3:00 p.m. on Aviv 14.

From the sixth hour of daylight (noon) until the ninth hour (3:00 p.m.), darkness came over the land; and it was about the ninth hour (about 3:00 p.m.) that Jesus died (Matthew 27:45-50; Mark 15:33-37; Luke 23:44-46).  Thus, Jesus died at the same time that Israel’s high priest slaughtered the Passover lamb in the temple.  This correlation indicates that Jesus was the ultimate Passover Lamb for humanity (1 Corinthians 5:7b).
