It is true that this promise is very similar to others, to which I have assigned a peculiar place, but it has this difference, that, in inviting the people to be zealous in keeping the Law, it sets before their eyes the effect of the covenant already made with their fathers, in order that they may more cheerfully receive the Law. Therefore there was good reason for my saying just before that the promises which refer to the past have their appropriate place here, where their minds are prepared to obey God and keep His Law, because the race of Abraham God had chosen to Himself, that tie may continually visit them with His favor. He therefore promises them His blessing on their bread and water and bodily health, for on these three things depend the condition of our present life. Two other things He adds — fecundity in generation, and length of days. The sum is, that they had been prevented by God’s loving-kindness, in order that they might willingly honor Him, and that now all He had promised them was close at hand, if only they responded to His grace. But, although the fertility of the land was great, and its productions various and abundant, no mention is here made, as in other places, of wine or oil, but only of simple food, as if He had said that the necessary supports of life should not be wanting to them.
