John and Doves,
AC has many names. Tyre is one of them. We learn this from Ezekiel 28, a prophecy against Tyrus. Few highlights about Tyrus' character.
"I am a God, I sit in the seat of God, in the midst of the seas;"
"Because thou hast set thine heart as the heart of God;"
This Tyrus has the same character of the man of sin in 2 Thessalonians 2:4. They both claim that they are God. Basically, Tyrus and man of sin are the same person.
Consider why does God name Antichrist as Tyrus, we find Tyrus trafficking with all nations' commerce and merchandise in Ezekiel 27. My belief is AC shall set up Tyre as his commerce center after he revives Roman Empire, with Babylon his religious hub. When he does that, God calls him Tyrus.
But my focus is on Isaiah 23:15-17.
Isaiah 23:15 And it shall come to pass in that day, that Tyre shall be forgotten seventy years, according to the days of one king: after the end of seventy years shall Tyre sing as an harlot.
"Tyre shall be forgotten seventy years" speaks of his age. Before he reaches the age of 70 years old, he seems fine before God. But when he reaches the end of his 70 years, he shall sing as an harlot. While virgin stands for faithful servant before God, a harlot speaks of an unfaithful servant, who opposes God.
Now, there are two possibilities concerning his age. The first one is when he appears after the rapture, he is 70 years old. This is the first year of tribulation. The second scenario is he is 70 years old when he sits in God's temple, imagine himself being God. This is a mid-trib event. I am leaning toward the second scenario because when he sits in God's temple, imagine himself being God, it matches with what God says about him, that is, he sings as an harlot by opposing God, even desires to replace God.
But I also won't rule out the first scenario especially I have found out Cardinal Peter Erdo's birthday is only one day away from my rapture day June 26 2022. And he shall reach the end of his 70 years on June 26 2022.
