And when he opened the second seal, I heard the second living creature saying, ‘Come and behold!’
and there went forth another horse – red, and to him who is sitting upon it, there was given to him to take the peace from the land, and that one another they may slay, and there was given to him a great sword.
Isaiah 27:1 says God's sword is a great sword:
In that day lay a charge doth Jehovah, With his sword – the sharp, and the great, and the strong, On leviathan – a fleeing serpent, And on leviathan – a crooked serpent, And He hath slain the dragon that is in the sea.
Ezekiel 30:22-24 quotes God saying he will give his sword to the king of Babylon:
Therefore, thus said the Lord Jehovah: Lo, I am against Pharaoh, king of Egypt, And I have broken his arms, The strong one and the broken one, And have caused the sword to fall out of his hand,
And scattered the Egyptians among nations, And I have spread them through lands,
And strengthened the arms of the king of Babylon, And I have given My sword into his hand, And I have broken the arms of Pharaoh, And he groaned the groans of a pierced one – before him.
And I have strengthened the arms of the king of Babylon, And the arms of Pharaoh do fall down, And they have known that I am Jehovah, In My giving My sword into the hand of the king of Babylon, And he hath stretched it out toward the land of Egypt.
And I have scattered the Egyptians among nations, And I have spread them through lands, And they have known that I am Jehovah!’
So is the horseman in Revelation 6:3-4 referring to Nebuchadnezzar king of Babylon?
