Who are they in Amos 9:2?
Though they dig into hell, thence shall mine hand take them; though they climb up to heaven, thence will I bring them down: (KJV)
It looks like "they" refers to the posts in the previous verse:
I saw the Lord standing upon the altar: and he said, Smite the lintel of the door, that the posts may shake: and cut them in the head, all of them; and I will slay the last of them with the sword: he that fleeth of them shall not flee away, and he that escapeth of them shall not be delivered. (KJV)
However, I have no idea what those posts mean.
