The Passover lamb

The Passover and the Exodus (1446 BC) to The Last Supper (AD 30–33): ~1,480 years in the Modern reckoning, ~1,520 years in the Traditional.

Israel kills the Passover lamb at twilight; on the day the Passover lamb is sacrificed, Jesus sits down to the Passover meal with his disciples.

On the first day of the Feast of Unleavened Bread, when the Passover lamb was to be sacrificed, Jesus’ disciples asked Him, “Where do You want us to prepare for You to eat the Passover?”
Mark 14:12
You must keep it until the fourteenth day of the month, when the whole assembly of the congregation of Israel will slaughter the animals at twilight.
