After two days was the feast of the passover, and of unleavened bread: and the chief priests and the scribes sought how they might take him by craft, and put him to death.

Though the evangelists generally use the words pasch and azymes promiscuously, yet St. Mark distinguishes them, being really different. The pasch is used for the 14th day of the moon of the first month. But the 15th day, on which they departed out of Egypt, was the feast of the azymes, or the unleavened bread; which continued seven days, till the 21st day of the moon inclusive. (Ven. Bede)
Pasch is also used for the sabbath day within the seven days of the solemnity; (John xix. 14.) and also for all the sacrifices made during the seven days of the feast.
