De Somniis (lib. i-ii)

But there is in the Deity such an excessive degree of stability and firmness, that he gave even to the most excellent natures a share of his durability as his most excellent possession: and presently afterwards he, the most ancient author of all things, namely God, says that he is about to erect firmly his covenant full of grace (and that means his law and his word) in the soul of the just man as on a solid foundation, which shall be an image in the likeness of God, when he says to Noah, "I will establish my covenant with thee." [*](Genesis ix. 10. )

And besides this, he also indicates two other things, one that justice is in no respect different from the covenant of God, the other that other beings bestow gifts which are different from the persons who receive them; but God gives not only those gifts, but he gives also the very persons who receive them to themselves, for he has given me to myself, and every living being has he given to himself; for the expression, "I will establish my covenant with thee," is equivalent to, I will give thee to thyself.
