'Unleavened' in the Bible

On the first day of the Unleavened Bread the disciples came to Jesus with the question, "Where shall we make preparations for you to eat the Passover?"

It was now two days before the Passover and the feast of Unleavened Bread, and the High Priests and Scribes were bent on finding how to seize Him by stratagem and put Him to death.

On the first day of the feast of Unleavened Bread--the day for killing the Passover lamb--His disciples asked Him, "Where shall we go and prepare for you to eat the Passover?"

Meanwhile the Festival of the Unleavened Bread, called the Passover, was approaching,

When the day of the Unleavened Bread came--the day for the Passover lamb to be sacrificed--

Finding that this gratified the Jews, he proceeded to seize Peter also; these being the days of Unleavened Bread.

But we ourselves sailed from Philippi after the days of Unleavened Bread, and five days later joined them in the Troad, where we remained for a week.
