'Feast of the Passover' in the Bible

Thou shalt not offer the blood of my sacrifice with leavened bread; neither shall the sacrifice of the feast of the passover be left unto the morning.

Now after two days was the feast of the passover and the unleavened bread: and the chief priests and the scribes sought how they might take him with subtlety, and kill him:

And his parents went every year to Jerusalem at the feast of the passover.

Now before the feast of the passover, Jesus knowing that his hour was come that he should depart out of this world unto his Father, having loved his own that were in the world, he loved them unto the end.
