'Feet' in the Bible

And the angel said to me, “What do you see?” And I answered, “I see a flying scroll; its length is twenty cubits (thirty feet) and its width is ten cubits (fifteen feet).”

In that day His feet shall stand on the Mount of Olives, which lies before Jerusalem on the east; and the Mount of Olives will be split in half from the east to the west by a very large valley, and half of the mountain will move toward the north and half of it toward the south.

Now this will be the plague with which the Lord shall strike all the peoples that have warred against Jerusalem: Their flesh will rot while they stand on their feet, and their eyes will rot in their sockets, and their tongue will rot in their mouth.
