'Feast of the Passover' in the Bible

Thou shall not offer the blood of my sacrifice with leavened bread, nor 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.

Now before the feast of the Passover, Jesus, having seen that his hour has come that he would depart out of this world to his Father, having loved his own in the world, he loved them to the end.
