No body, no power, can exempt them from the obligations of that eternal law.

Those are so great, and so strong, in the case of promises, that omnipotency itself can be tied by them.
Grants, promises, and oaths, are bonds that hold the Almighty: whatever some flatterers say to princes of the world, who all together, with all their people joined to them, are, in comparison of the great God, but as a drop of the bucket, or a dust on the balance, inconsiderable, nothing! Sect.196.The short of the case in conquest is this: the conqueror, if he have a just cause, has a despotical right over the persons of all, that actually aided, and concurred in the war against him, and a right to make up his damage and cost out of their labour and estates, so he injure not the right of any other.
