Genesis 9:15

15.And I will remember my covenant. Moses, by introducing God so often as the speaker, teaches us that the word holds the chief place, and that signs are to be estimated by it. (294) God, however, speaks after the manner of men, when he says, that at the sight of the rainbow he will remember his covenant. But this mode of speaking has reference to the faith of men, in order that they may reflect, that God, whenever he stretches out his arch over the clouds, is not unmindful of his covenant.
