The Birth of Jesus Christ.
Since Jesus was conceived six months after John the Baptist, and we have established a likely date for John’s birth, we need only move six months farther down the Jewish calender to arrive at a likely date for the birth of Jesus. From the 15th day of the 1st month, Nisan, we go to the 15th day of the 7th month, Tishri. And what do we find on that date? It is the festival of Tabernacles! The 15th day of Tishri begins the third and last festival of the year to which all the men of Israel were to gather in Jerusalem for Temple services. (Lev 23:34)
Immanuel.
Isa 7:14 Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel.
Immanuel means “God with us”. The Son of God had come to dwell with, or tabernacle on earth with His people.
John 1:14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
The word in the Hebrew for dwelt is succah and the name of the Feast of Tabernacles in Hebrew is Sukkot, a festival of rejoicing and celebration:
Luke 2:7 And she brought forth her firstborn son, and wrapped him in swaddling clothes, and laid him in a manger; because there was no room for them in the inn.
Luke 2:8 And there were in the same country shepherds abiding in the field, keeping watch over their flock by night.
Luke 2:9 And, lo, the angel of the Lord came upon them, and the glory of the Lord shone round about them: and they were sore afraid.
Luke 2:10 And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people.
Luke 2:11 For unto you is born this day in the city of David a Saviour, which is Christ the Lord.
Why was there no room at the inn? Bethlehem is only about 5 miles from Jerusalem, and all the men of Israel had come to attend the festival of Tabernacles as required by the law of Moses. Every room for miles around Jerusalem would have been already taken by pilgrims, so all that Mary and Joseph could find for shelter was a stable.
Also of note is the fact that the Feast of Tabernacles is an eight day feast (Lev 23:36, 39). Why eight days? It may be because an infant was dedicated to God by performing circumcision on the eighth day after birth:
Luke 2:21 And when eight days were accomplished for the circumcising of the child, his name was called JESUS, which was so named of the angel before he was conceived in the womb.
So the infant Jesus would have been circumcised on the eighth and last day of the Feast of Tabernacles, a Sabbath day. The Jews today consider this a separate festival from Tabernacles, and they call it Shemini Atzeret.
