Strange that you mentioned Mathias as my wife and I just read the 1.st chapter of Acts this morning. The lot fell to Mathias to replace Judas as the 12th Apostle.
I find it interesting Judas falling backward slain in the spirt is used to represent the "spirit of judgement" Those who follow after a false gospel, the poison of false prophecy .
The tribe of Dan. Dan literally means "God is my judge;" It is used to represent the spirit of judgement the letter of the law death representing those who fall backward or break the neck in hanging, the judgement .
Both the tribe of Dan is missing from the description of the bride of Christ in Revelation. Tribes as gates into the city prepared as the bride are used to represent old testament saints the bride of Christ. And Judas missing from the twelve apostles used to represent saints on this side of the reformation as wall of the same city is missing
Dan "God is my judge;" represents the letter of the law death . Death will not be part of the new order. And Judas used as a witness to the law will not enter
Genesis 49:15-17 King James Version (KJV) And he saw that rest was good, and the land that it was pleasant; and bowed his shoulder to bear, and became a servant unto tribute.
Dan shall
judge his people, as one of the tribes of Israel. Dan shall be a
serpent by the way, an
adder in the path, that biteth the horse heels, so that
his rider shall
fall backward.
John 18:5-7 King James Version (KJV) They answered him, Jesus of Nazareth. Jesus saith unto them,
I am he. And
Judas also, which betrayed him, stood with them.
As soon then as he had said unto them,
I am he, they
went backward, and fell to the ground.
The spirit of judgement. . slain in the Spirit is shown by the power of (I am he) the tongue of death .Death as the judgement of God will not enter the new order.
