I just did a quick count-down and count-up and came to this conclusion on this fourth day of Hanukkah: if Jesus died in 30 AD (which is 40 years before the Temple’s destruction; mentioned in the Babylonian Talmud, Yoma 39b, and also referred to in the Jerusalem Talmud; see http://www3.telus.net/public/kstam/en/temple/details/evidence.htm ), and was 33 1/2 yrs old (having begun His 3 1/2 yr public ministry when He was about 30 years old, then He was born in Dec., 5 B.C., by my reckoning. https://www.streamsinthenegev.com/school-of-fish/conception-and-birth-of-john-the-baptiser-and-jesus-the-messiah/ (If He were born in 2 B.C., because of Herod dying in 1 BC instead of in 4 BC before Passover, then His death would have been in 33 AD, which reduces the forty years from the rent veil till the Temple’s destruction). The magi from the East could have seen His star up to a couple of years before they actually arrived in Bethlehem, Israel.
Yeshua, as the Passover Lamb, began His last week (Passion Week) in Jerusalem on Sunday, the first day of the week (the day after the Sabbath), which would have been the 10th day of the first month (Nisan) leading up to the Passover. He was “examined” until the 14th of the month (Ex 12), and was found without spot or blemish by the people, by the Jewish rulers (they needed false witnesses in order to “make” Him guilty and condemn Him), and by Pilate and Herod. He was crucified and died on the afternoon of the 14th of the month, Thursday. This also fulfills the prophecy connected with Jonah, that Jesus would be in the heart of the Earth for three days and three nights, rising early on the first day of the week as the first-fruits from among the dead, the day after the Sabbath.
“Good Friday” would have been a Sabbath as being the first full day of Passover (Lev 23); and I believe it is called Good Friday because believers — after the fact (and the Holy Spirit from the beginning) — would have come to understand that what took place the day before was actually the greatest victory of all ages and the essence of the Good News and the New Covenant: Jesus Christ came into the world to save sinners, and to bury our sins with Him, fulfilling the beginning of the Feast of Unleavened Bread at the appointed time of the 15th day of the first month! HalleluYah!
The Hebrew/Jewish/Messianic roots of New Testament faith are found in the Word of God given to and through Israel.
