'Famine' in the Bible

And there is a famine in the days of David three years, year after year, and David seeketh the face of Jehovah, and Jehovah saith, 'For Saul and for the bloody house, because that he put to death the Gibeonites.'

And Gad cometh in unto David, and declareth to him, and saith to him, 'Do seven years of famine come in to thee in thy land? or three months art thou fleeing before thine adversary -- and he pursuing thee? or are three days' pestilence in thy land? now, know and see what word I take back to Him sending me.'
