Luke 22:1

Now the feast of unleavened bread drew nigh ,.... Which lasted seven days; during which the Jews eat their bread without leaven, in commemoration of the haste in which they went out of Egypt; being such, that they had not time to leaven their dough, but took it with their kneadingtroughs along with them, as it was; and as figurative of the unleavened bread of sincerity and truth, with which the Gospel feast is to be kept; see Exodus 12:34 .

Which is called the passover ; because the Lord passed over the houses of the Israelites, when he slew all the firstborn in Egypt; now the time of this feast drew near, when the conspiracy was formed against the life of Christ: Matthew and Mark are more precise, and suggest, that it was two days before the passover; see Matthew 26:2 .
