American Standard Version (ASV):
And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east; and the mount of Olives shall be cleft in the midst thereof toward the east and toward the west, [and there shall be] a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.
King James Version (KJV):
And his feet shall stand in that day upon the mount of Olives, which [is] before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, [and there shall be] a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.
