'Feet' in the Bible

“What do you see?” he asked me.“I see a flying scroll,” I replied, “30 feet long and 15 feet wide.”

For see, I will put a sheep-keeper over the land, who will have no care for that which is cut off, and will not go in search of the wanderers, or make well what is broken, and he will not give food to that which is ill, but he will take for his food the flesh of the fat, and let their feet be broken.

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.

And this shall be the plague wherewith the LORD will smite all the people that have fought against Jerusalem; Their flesh shall consume away while they stand upon their feet, and their eyes shall consume away in their holes, and their tongue shall consume away in their mouth.
