'Unleavened Bread' in the Bible

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

It was now two days before the festival of the Passover and of Unleavened Bread. And the high priests and scribes were casting about for a way to arrest him by stealth and put him to death,

On the first day of the festival of Unleavened Bread, on which it was customary to kill the Passover lamb, Jesus' disciples said to him, "Where do you wish us to go and make the preparations for you to eat the Passover supper?"

The festival of Unleavened Bread, which is called the Passover, was approaching.

When the day of Unleavened Bread came, on which the Passover lamb had to be sacrificed,

and when he saw that this gratified the Jews, he proceeded to arrest Peter too, at the time of the festival of Unleavened Bread.

while we sailed from Philippi after the festival of Unleavened Bread, and joined them at Troas five days later. There we stayed a week.

So let us keep the festival, not with old yeast nor with the yeast of vice and wickedness, but with the unleavened bread of purity and truth.
