As I have just said, God here enhances the sin of the people by a twofold comparison; for when one can draw water in his own field, and find there a spring, what folly will it be for him to run to a distance to seek water? And then, when water does not spring up near, but flows from a distance in a pure and cold stream, who will not be satisfied with such water? and if he seeks to find the spring, will not all laugh at such madness? Now God was like a living fountain, and at Jerusalem was the spring where the Jews might drink to their full; and God’s blessings flowed also to them as it were through various channels, so that nothing was wanting to them. We then see that here is condemned a twofold madness in the people, that they despised God’s kindness which was near at hand, as though one close to Mount Libanus refused its cold waters, or as though one would not draw water from a river without going to the spring-head. Since then God offered himself to them in every way, and presented his bounty to them, it was a madness extremely base and inexcusable to reject flowing waters and the fountain itself.
