'Feast of the Passover' in the Bible

You shall not slaughter the blood of My sacrifice with leaven. Neither shall the sacrifice of the feast of the Passover be left to the morning.

And His parents went to Jerusalem every year at the Feast of the Passover.

And before the feast of the Passover, when Jesus knew that His hour had come when He should depart out of this world to the Father, having loved His own in the world, He loved them to the end.
