All bills for raising revenue shall originate in the house of representatives. The governor, auditor, and attorney-general shall, before each regular session of the legislature, prepare a general revenue bill to be submitted to the legislature, for its information, and the secretary of state shall have printed for the use of the legislature a sufficient number of copies of the bill so prepared, which the governor shall transmit to the house of representatives as soon as organized, to be used or dealt with as that house may elect. The senate may propose amendments to revenue bills. No revenue bill shall be passed during the last five days of the session.
