When is Satan bound?
Before or after Armageddon?
After Armageddon, considering Armageddon is where the armies assemble themselves, move down and come up against Jerusalem, holding the Jews there as hostage, as part of their plan in making war against Jesus.
Psalms 2:
1 Why do the heathen rage, and the people imagine a vain thing?
2 The kings of the earth set themselves, and the rulers take counsel together, against the LORD, and against his anointed,
saying,
3 Let us break their bands asunder, and cast away their cords from us.
4 He that sitteth in the heavens shall laugh: the Lord shall have them in derision.
5 Then shall he speak unto them in his wrath, and vex them in his sore displeasure.
________________________________________________________________At the scene, as Jesus is standing on the mount of olives, and on the temple mount the false prophet and the beast are about to be cast alive into the lake of fire; and the temple set on fire to expose the abomination of desolation image placed there. Then the outer facade of the image of the beast will be burnt up, brought to ashes to expose Satan to the whole world - fulfilling Ezekiel 28:17-18. All three are going to be made to bow and confess that Jesus is Lord.
17 Thine heart was lifted up because of thy beauty, thou hast corrupted thy wisdom by reason of thy brightness:
I will cast thee to the ground,
I will lay thee before kings, that they may behold thee.
18 Thou hast defiled thy sanctuaries by the multitude of thine iniquities, by the iniquity of thy traffick; therefore will I bring forth a fire from the midst of thee, it shall devour thee, and
I will bring thee to ashes upon the earth in the sight of all them that behold thee.
Then Jesus will destroy the armies surrounding Jerusalem, who will be immobilized and see it all. Then the lone angel descends binds up Satan and he is cast into the bottomless pit.
