'Rod' in the Bible

But Jonathan heard not when his father charged the people with the oath: wherefore he put forth the end of the rod that was in his hand, and dipped it in an honeycomb, and put his hand to his mouth; and his eyes were enlightened.

Then Saul said to Jonathan, Tell me what thou hast done. And Jonathan told him, and said, I did but taste a little honey with the end of the rod that was in mine hand, and, lo, I must die.
