'Ribs' in the Bible

And Jehovah Elohim caused a deep sleep to fall upon Man; and he slept. And he took one of his ribs and closed up flesh in its stead.

And behold, another beast, a second, like unto a bear, and it raised up itself on one side; and it had three ribs in its mouth between its teeth; and they said thus unto it: Arise, devour much flesh.
