VII. (1.37) Therefore the heaven, which is the archetypal organ of music, appears to have been arranged in a most perfect manner, for no other object except that the hymns sung to the honour of the Father of the universe, might be attuned in a musical manner; and we hear that virtue, that is to say, Leah, [Ge 29:35.] after the birth of her fourth son, was no longer able to bring forth any more, but restrained, or perhaps I should say, was restrained, as to her generative powers; for she found, I conceive, all her generative power dry and barren, after she had brought forth Judah, that is to say, "confession," the perfect fruit: (1.38) and the phrase, "Leah desisted from bearing children," differs in no respect from the statement, that the children of Isaac found no water in the fourth Well."[Ge 26:32.] Since it appears from both these figurative expressions, that every creature thirsts for God, by whom all their births take place, and from whom nourishment is bestowed to them when they are born. (1.39) Perhaps therefore some petty cavilling critics will imagine that all this statement about the digging of the wells is a superfluous piece of prolixity on the part of the lawgiver: but those who deserve a larger classification, being citizens not of some petty state but of the wide world, being men of more perfect wisdom, will know well that the real question is not about the four wells, but about the parts of the universe that the men who are gifted with sight, and are fond of contemplation exercise their powers of investigation; namely, about the earth, the water, the air, and the heaven. (1.40) And examining each of these matters with the most accurately refined conception, in three of them they have found some things within the reach of their comprehension; on which account they have given these names, injustice, enmity, and latitude to what they have discovered. But in the fourth, that is to say in heaven, they have found absolutely nothing whatever, which they could comprehend; as we explained a little time ago: for the fourth is found to be a well destitute of water, and dry; and for the reason above mentioned it is called a well.
