And after two days it was the Passover and the Feast of Unleavened Bread. And the chief priests and the scribes sought how they might take Him by craft and kill Him.

And the first day of Unleavened Bread, when they killed the passover, His disciples said to Him, Where do You desire that we go and prepare that You may eat the passover?

And the Feast of Unleavened Bread, which is called the Passover, drew near.

And the day of the Unleavened Bread came, when the passover must be killed.

And because he saw it pleased the Jews, he went further to seize Peter also. (And they were days of Unleavened Bread.)

And after the days of Unleavened Bread, we sailed away from Philippi and came to them at Troas in five days, where we stayed seven days.

Therefore let us keep the feast; not with old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.
