Let's begin at the first Passover. This was the night in which the LORD smote all the firstborn in Egypt. The Israelites were instructed to kill a lamb and strike its blood on the two side posts and the upper door post (Exodus 12:4, 5). Let us now see what the Bible says concerning the first passover, and the days of unleavened bread.
Exodus 12:13-18:
"And the blood shall be to you for a token upon the houses where ye are: and when I see the blood, I will pass over you, and the plague shall not be upon you to destroy you, when I smite the land of Egypt.
14 And this day shall be unto you for a memorial; and ye shall keep it a feast to the LORD throughout your generations; ye shall keep it a feast by an ordinance for ever.
15 Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whosoever eateth leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.
16 And in the first day there shall be an holy convocation to you; no manner of work shall be done in them, save that which every man must eat, that only may be done of you.
17 And ye shall observe the feast of unleavened bread; for in this selfsame day have I brought your armies out of the land of Egypt: therefore shall ye observe this day in your generations by an ordinance for ever.
18 In the first month, on the fourteenth day of the month at even ye shall eat unleavened bread, until the one and twentieth day of the month at even."
Here in Exodus 12:13 we see how the passover got its name. The LORD said that He would "pass over" all of the houses which had the blood of the lamb marking the door.
After the passover (Exodus 12:13, 14), we find that seven days shall be fulfilled in which the Jews were to eat unleavened bread. These are the days of unleavened bread!
In verse 18 we see that dates for the observance were April 14th through the 21st. This religious observance is stated more clearly in Numbers 28:16-18:
"And in the fourteenth day of the first month is the passover of the LORD.
17 And in the fifteenth day of this month is the feast: seven days shall unleavened bread be eaten.18 In the first day shall be an holy convocation;ye shall do no manner of servile work therein:"
In verse 16 we see that the passover is only considered to be the 14th of the month. On the next morning, the 15th begins the "days of unleavened bread."
We see then, from studying what the BIBLE has to say concerning the subject that the order of events went as follows:
- On the 14th of April the lamb was killed. This is the passover. No event following the 14th is ever referred to as the passover.
- On the morning of the 15th begins the days of unleavened bread, also known as the feast of unleavened bread.
It must also be noted that whenever the passover is mentioned in the New Testament, the reference is always to the meal, to be eaten on the night of April 14th not the entire week. The
days of unleavened bread are NEVER referred to as the Passover. (It must be remembered that the angel of the Lord passed over Egypt on one night, not seven nights in a row.
Now let us look at Acts 12:3, 4:
"And because he saw it pleased the Jews, he proceeded further to take Peter also. (Then were the days of unleavened bread.) And when he had apprehended him, he put him in prison, and delivered him to four quaternions of soldiers to keep him; intending after Easter to bring him forth to the people."
Verse 3 shows that Peter was arrested during the days of unleavened bread (April 15-21).
The Bible says: "Then were the days of unleavened bread." The passover (April 14th) had already come and gone. Herod could not possibly have been referring to the passover in his statement concerning Easter. The next Passover was a year away! But the pagan holiday of Easter was just a few days away. Remember! Herod was a pagan Roman who worshipped the "queen of heaven". He was NOT a Jew. He had no reason to keep the Jewish passover. Some might argue that he wanted to wait until after the passover for fear of upsetting the Jews. There are two grievous faults in this line of thinking.
First, Peter was no longer considered a Jew. He had repudiated Judaism. The Jews would have no reason to be upset by Herod's actions.
Second, he could not have been waiting until after the passover because he thought the Jews would not kill a man during a religious holiday. They had killed Jesus during passover (Matthew 26:17-19, 47). They were also excited about Herod's murder of James. Anyone knows that a mob possesses the courage to do violent acts during religious festivities, not after.
In further considering Herod's position as a Roman, we must remember that the Herods were well known for celebrating (Matthew 14:6-11). In fact, in Matthew chapter 14 we see that a Herod was even willing to kill a man of God during one of his celebrations.
It is easy to see that Herod, in Acts 12, had arrested Peter during the days of unleavened bread, after the passover. The days of unleavened bread would end on the 21st of April. Shortly after that would come Herod's celebration of pagan Easter. Herod had not killed Peter during the days of unleavened bread simply because he wanted to wait until Easter. Since it is plain that both the Jews (Matthew 26:17-47) and the Romans (Matthew 14:6-11) would kill during a religious celebration, Herod's opinion seemed that he was not going to let the Jews "have all the fun." He would wait until his own pagan festival and see to it that Peter died in the excitement.
