'Feet' in the Bible

A wind sent by the Lord came up and blew quail in from the sea; it dropped them at the camp all around, three feet off the ground, about a day’s journey in every direction.

And the children of Israel said unto him, We will go by the high way: and if I and my cattle drink of thy water, then I will pay for it: I will only, without doing any thing else, go through on my feet.
