Any refunding bonds issued under the authority of this article are payable from the revenues out of which the bonds to be refunded thereby were payable, or from other moneys or the principal of and interest on or other investment yield from, investments or proceeds of bonds or other applicable funds and moneys, including investments of proceeds of any refunding bonds, and are subject to the provisions contained in section nine of this article and shall be secured in accordance with the provisions of sections nine and ten of this article.
