'Unleavened Bread' in the Bible

On the first day of the Festival of the Unleavened Bread, the disciples came up to Jesus, and said: "Where do you wish us to make preparations for you to eat the Passover?"

It was now two days before the Festival of the Passover and the Unleavened bread. The Chief Priests and the Teachers of the Law were looking for an opportunity to arrest Jesus by stealth, and to put him to death;

On the first day of the Festival of the Unleavened bread, when it was customary to kill the Passover lambs, his disciples said to Jesus: "Where do you wish us to go and make preparations for your eating the Passover?"

The Feast of the Unleavened Bread, known as the Passover, was near.

When the day of the Festival of the Unleavened Bread came, on which the Passover lambs had to be killed,

And, when he saw that the Jews were pleased with this, he proceeded to arrest Peter also. (This was during the Festival of the Unleavened Bread.)

Therefore let us keep our festival, not with the leaven of former days, nor with the leaven of vice and wickedness, but with the unleavened bread of sincerity and truth.
