The utmost good faith shall always be observed towards the Indians; their lands and property shall never be taken from them without their consent; and in their property, rights, and liberty they never shall be invaded or disturbed, unless in just and lawful wars authorized by Congress; but laws founded in justice and humanity shall, from time to time, be made, for preventing wrongs being done to them, and for preserving peace and friendship with them.
ARTICLE IV.

The said territory, and the States which may be formed therein, shall forever remain a part of this confederacy of the United States of America, subject to the Articles of Confederation, and to such alterations therein as shall be constitutionally made; and to all the acts and ordinances of the United States in Congress assembled, conformable thereto.

The inhabitants and settlers in the said territory shall be subject to pay a part of the Federal debts, contracted, or to be contracted, and a proportional part of the expenses of government to be apportioned on them by Congress, according to the same common rule and measure by which apportionments thereof shall be made on the other States; and the taxes for paying their proportion shall be laid and levied by the authority and direction of the legislatures of the district, or districts, or new States, as in the original States, within the time agreed upon by the United States in Congress assembled.

The legislatures of those districts, or new States, shall never interfere with the primary disposal of the soil by the United States in Congress assembled, nor with any regulations Congress may find necessary for securing the title in such soil to the bona-fide purchasers.

No tax shall be imposed on lands the property of the United States; and in no case shall non-resident proprietors be taxed higher than residents.
