He calls them too the oaths to the tribes: for though God had spoken to Abraham and afterwards to Moses, yet the promise was deposited in the hands of Abraham, and of the patriarchs, and afterwards in those of Moses, that the people might understand that it belonged equally to them; for it would have been no great matter to promise what we read of to a few men only. But Abraham was as it were the depository; and it was a certain solemn stipulation made with his whole race. We hence see why the Prophet here mentions the tribes rather than Abraham, or the patriarchs or Moses. He had indeed a special regard to those of his own time, in order to confirm them, that they might not doubt but that God would extend to them also the same power. How so? Because God had formerly wrought in a wonderful manner for the deliverance of his people. Why? That he might prove himself to be true and faithful. In what respect? Because he had said, that he would be the protector of his people; and he did not adopt a few men only, but the whole race of Abraham. Since it was so, why should not his posterity hope for that which they knew was promised to their fathers? for the truth of God can never fail. Though many ages had passed away, the faith of his people ought to have remained certain, for God intended to show himself to be the same as he had been formerly known by their fathers.
