'Passover' in the Bible

It was now two days before the feast of the Passover and the unleavened bread: and the chief priests and the scribes made designs how they might take him by deceit and put him to death:

And on the first day of unleavened bread, when the Passover lamb is put to death, his disciples said to him, Where are we to go and make ready for you to take the Passover meal?

And wherever he goes in, say to the owner of the house, The Master says, Where is my guest-room, where I may take the Passover with my disciples?

And the disciples went out and came into the town, and saw that it was as he had said: and they made ready the Passover.
