Isa 27:1 In that day the LORD with his sore and great and strong sword shall punish leviathan the piercing serpent, even leviathan that crooked serpent; and he shall slay the dragon that is in the sea.
I see two serpents here; both are evil and of the devil. Leviathan, the piercing serpent, even leviathan that crooked serpent shall be punished. The serpent in the garden of Eden was the symbol of satan. We can assume that satan is Leviathan, the piercing serpent.
The Hebrew word: bariyach, was translated: piercing, but it also means fleeing. That fleeing crooked serpent, was trying to escape Jesus as he came with the sword of the word of God; His sore and great and strong sword.
Rev 19:15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
Rev 19:16 And he hath on his vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS.
The angels caught the serpent, satan, and he was cast into the bottomless pit for a thousand years, but he was not yet destroyed.
Rev 20:1 And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.
Rev 20:2 And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years,
Rev 20:3 And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
Another serpent came from the sea. This is the antichrist beast: and he shall slay the dragon that is in the sea.
Rev 13:1 And I stood upon the sand of the sea, and saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy.
Rev 13:6 And he opened his mouth in blasphemy against God, to blaspheme his name, and his tabernacle, and them that dwell in heaven.
Rev 13:7 And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.
Rev 13:8 And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world.
Rev 13:9 If any man have an ear, let him hear.
His end came upon Christ's return, his judgment was swift.
Rev 19:19 And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army.
Rev 19:20 And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.
They were so evil, that they went straight to the lake of fire, no hearing or trial. People receive judgment before God, these were as fallen angels, thoroughly taken over by satan, despised of God and receiving quick wrath in the torment of the lake of fire. Many of the world are aligning themselves with this antichrist spirit. Let us give ourselves totally to God, through Jesus Christ our Lord. Let none fall away that proclaim his holy name. Leviathan that twisting serpent will twist truth and deceive many in these last days. Let us take up the Lord's sword. The Holy Word of God, the Holy Bible. Speak it to the serpent and his followers. Let the sword of God do the piercing.
Heb 4:12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
