More proof that the tree is Jesus' body:
The scriptures about the 'Branch' are about Jesus.
"Behold, the days are coming,'' says the Lord, "That I will raise to David a Branch of righteousness; a King shall reign and prosper, and execute judgment and righteousness in the earth. In His days Judah will be saved, and Israel will dwell safely; now this is His name by which He will be called: THE LORD OUR RIGHTEOUSNESS. Jeremiah 23:5-6 and: `Behold, the days are coming,' says the Lord, `that I will perform that good thing which I have promised to the house of Israel and to the house of Judah: `In those days and at that time I will cause to grow up to David a Branch of righteousness; He shall execute judgment and righteousness in the earth. In those days Judah will be saved, and Jerusalem will dwell safely. And this is the name by which she will be called: THE LORD OUR RIGHTEOUSNESS. Jeremiah 33:14-16
We read throughout many books in the Old Testament about the 'Branch', which proves it is a prophecy about Jesus.
The sacrificial lamb of the Passover is also a prophecy about Christ. A lamb without blemish or spot, was to be chosen as a pure offering, and it’s blood was for a sign of God’s people to save them from destruction.
Now the blood shall be a sign for you on the houses where you are. And when I see the blood, I will pass over you; and the plague shall not be on you to destroy you when I strike the land of Egypt. `So this day shall be to you a memorial; and you shall keep it as a feast to the Lord throughout your generations. You shall keep it as a feast by an everlasting ordinance. Exodus 12:13-14
In the book of Colossians, the Apostle Paul gives a brief explanation that the festivals and Sabbaths of the Law were no longer the essentials of our religious practice, being “types” which pointed to the spiritual reality to be found in Jesus Christ: Therefore let no one judge you in food or in drink, or regarding a festival or a new moon or sabbaths, which are a shadow of things to come, but the substance is of Christ. Colossians 2:16-17
All the Old Testament holy days were about Jesus, who was to come.
Jesus is the Sabbath Rest.
That is something from the creation of the world in Genesis.
The Author of the book of Hebrews goes into greater detail on the aspect of the ritual law under Moses being only a “type” pointing to the more perfect law to be found in Christ Jesus: For if He were on earth, He would not be a priest, since there are priests who offer the gifts according to the law; who serve the copy and shadow of the heavenly things, as Moses was divinely instructed when he was about to make the tabernacle. For He said, "See that you make all things according to the pattern shown you on the mountain.'' Hebrews 8:4-5 and: For the law, having a shadow of the good things to come, and not the very image of the things, can never with these same sacrifices, which they offer continually year by year, make those who approach perfect. Hebrews 10:1.
God telling Abraham to sacrifice his son Isaac is about Jesus.
