Luke 22:2

The actions of the Jews were a shadow of our own. Accordingly if you ask of a Jew concerning the Passover, and the feast of unleavened bread, he will tell you nothing momentous, mentioning the deliverance from Egypt; whereas should a man inquire of me he would not hear of Egypt or Pharaoh, but of freedom from sin and the darkness of Satan, not by Moses, but by the Son of God;

Whose Passion the Evangelist being about to relate, introduces the figure of it, saying, Now the feast of unleavened bread drew nigh, which is called the Passover.

Now the Passover, which is called in Hebrew “Phase,” is not so named from the Passion, but from the passing over, because the destroying angel, seeing the blood on the doors of the Israelites, passed over them, and touched not their first-born. Or the Lord Himself, giving assistance to His people, walked over them. But herein is the difference between the Passover and the feast of unleavened bread, that by the Passover is meant that day alone on which the lamb was slain towards the evening, that is, on the fourteenth day of the first month, but on the fifteenth, when the Israelites went out of Egypt, followed the feast of unleavened bread for seven days, up to the twenty-first of the same month. Hence the writers of the Gospel substitute one indifferently for the other. As here it is said, The day of unleavened bread, which is called the Passover. But it is signified by a mystery, that Christ having suffered once for us, has commanded us through the whole time of this world which is passed in seven days, to live in the unleavened bread of sincerity and truth.

The Chief Priests set about their impious deed on the feast, as it follows, And the Chief Priests and Scribes, &c. Moses ordained only one Priest, at whose death another was to be appointed. But at that time, when the Jewish customs had begun to fall away, there were many made every year. These then wishing to kill Jesus, are not afraid of God, lest in truth the holy time should aggravate the pollution of their sin, but every where fear man. Hence it follows, For they feared the people.

Not indeed that they apprehended sedition, but were afraid lest by the interference of the people He should be taken out of their hands. And these things Matthew reports to have taken place two days before the Passover, when they were assembled in the judgment hall of Caiaphas.
