Yahchanan 13:1; “Now before the Feast of Passover, when Yahshua knew that His hour had come that He should depart out of this world to the Father, having loved His own who were in the world, He loved them to the end.”

Yahchanan 13:2; “And supper being ended, the devil already having put it into the mind of Yahdah Iscariot, son of Simon, to betray Him.”

These verses, 13:1-2, are part of the story of Yahshua’s Memorial Supper, held the evening that He is taken captive, which was the 10th of Aviv, thus fulfilling the Law of Exodus 12:3.

Exodus 12:3; “Speak to all the congregation of Israyl, saying; On the Tenth Day of this First Moon, each man is to take a lamb for his family, one for each household.'”

Exodus 12:6; “And you must keep it until the Fourteenth Day of the same Moon: then the whole multitude of the congregation of Israyl shall kill it between the two evenings.”

Romans 10:4; “For Yahshua is the ultimate result of keeping the Law unto righteousness for everyone who believes.”
This next verse is when Yahdah goes out to get the priests and guards to arrest Yahshua in the Garden of Gethsemane.

Yahchanan 13:29; “For some thought, since Yahdah had the money bag, that Yahshua had said to him: ‘Buy those things that we have need of for the Feast; or that he should give something to the poor.'”

In these next two verses, Yahshua has already been taken captive on Friday night, held in prison on the Sabbath, judged by the Sanhedrin on Sunday and it is now Monday morning when Yahshua is taken to Pilate: Yahchanan 18:28; “Then they led Yahshua from Caiaphas to the hall of judgment; the Praetorium, and it was early in the morning. However, they did not go into the Praetorium
themselves, for they had to avoid ritual impurity in order to be able to eat the Passover Supper.”

Yahchanan 18:39; “But you have a custom, that I should release one to you at the Passover. Therefore, do you want me to release the King of the Yahdaim to you?”
This last verse to use the word Passover, tells which day it is that Yahshua is sacrificed:

Yahchanan 19:14; – “Now it was the Preparation Day for the Passover, and about the sixth hour; about 12:00 noon, that he said to the Yahdaim; ‘Behold your King!'”

After looking at every verse in the book of Yahchanan that has used the words “Passover” and “Feast”, it should be clear that they all refer to the same Passover at which Yahshua is sacrificed.
After looking at every verse with the words Passover and Feast in the book of Yahchanan, it should be clear that Yahshua attended the Feast of Tabernacles, the Feast of Dedication and then the Passover Feast of Unleavened Bread.
