Ambrose of Milan : With reference to the natural sense, you find it said in Ecclesiastes, "I made for myself pools of water to water from them a flourishing woodland." And do not be concerned that he said "pools" instead of "a well," because Moses said "the Well of Room-enough." For the man who has transcended this world with a pious mind is freed of all care and anxieties. There Ecclesiastes says "pools" with reason, for he sees that there is no abundance under the sun, but if anyone wishes to abound, let him abound in Christ. There remains for us the well in the mystical sense, and we find it in the Canticle of Canticles, where the Scripture says, "the fountain of gardens, the well of living water which runs with a strong stream from Lebanon." Indeed if you pursue the depth of the mysteries, the well appears to you to be mystical wisdom set in the deep, as it were. — On Isaac and the Soul Jerome : "I constructed pools from which to irrigate a grove of young trees. "The wood in glades and in forests, which is not fruit-bearing, are not nourished by rain from the sky, not by such rain waters but by water which is collected in pools from rivers. Even low-lying Egypt is situated low in the land like a vegetable patch, and is irrigated by waters, which come from Ethiopia. But the Promised Land which is mountainous and raised up waits for timely or late-coming rain from the sky. — Commentary on Ecclesiastes
