XLV. (153) And we must inquire the cause why the handmaid gave the servant drink from the fountain, but gave the camels water from the well. May it not perhaps be that the stream here signifies the sacred scripture itself, which irrigates the sciences, and that the well is rather akin to memory? For the depths which he has already mentioned, he produces by means of memory as it were out of a well; (154) and such persons as these one ought to admit because of the goodness of their natural disposition. But there are some men among those who practise virtue to whom the all-beneficent God has shown the way that leads to virtue, such that at first it is accounted rough, and steep, and difficult, but subsequently level and easy, having changed the bitterness of the wayfarer's labour to sweetness. And how he has wrought this change we will now tell. (155) When he led us forth out of Egypt, that is to say, out of the passions which excite the body, we, travelling in the desert, that is to say, in the path of pleasure, encamped in the place called Marah, a place which had no drinkable water, but where all the water was Bitter.[Ex 15:23.] For still the pleasures which are brought into action by means of the eyes, and ears, and belly, and the parts adjacent to the belly, were tempting to us, and charmed us exceedingly, sounding close to us. (156) When, therefore, we desired to be entirely separated from them, they dragged us back, exerting themselves in opposition to us, and entwining themselves round us, and soothing us with all kinds of juggling tricks and assiduous blandishments; so that we, yielding to their unremitting caresses, became alienated from and disinclined to labour, as something very bitter and intolerable, and designed to run back again to Egypt, that is to say, to the condition of an intemperate and lascivious life, if the Saviour had not speedily taken pity on us, and thrown a sweetening branch like a medicine upon our soul, causing it to love labour instead of hating it. (157) For he knew, inasmuch as he was our Creator, that we could not possibly survive any existing thing unless there were in us an intense love of doing so. Therefore, men never succeed in attaining any object that they desire if they pursue it without any connection with or consideration of fitness. But when friendship is added, and also a familiarity with the loved object, their endeavours then succeed rightly.
