The land of Egypt — what is revealed drinks; what is concealed does not drink. Eretz Yisrael — both the revealed and the concealed drink.
The land of Egypt drinks and then is sowed; Eretz Yisrael drinks and is sowed; is sowed and drinks. The land of Egypt does not drink every day; Eretz Yisrael drinks every day.
The land of Egypt — If one does not work in it (i.e., in the soil) with mattock and axe and (does not allow) sleep to escape his eyes, he has nothing of it. Not so Eretz Yisrael, but they (its inhabitants) sleep and the L-rd brings down rain for them. An analogy: A king is walking on the road, and, seeing a man of high estate, gives him a servant to serve him. He then sees another man of high estate, (having obviously been) preened and pampered, engaging in (mundane) labor, (all the while), conscious (of the nobility) of his ancestors — at which he says: I decree that you not toil with your own hands, and I will feed you (gratuitously). So, with all the lands, He gives them servants to serve them. Egypt drinks from the Nile; Bavel drinks from the Yuval. Not so Eretz Yisrael, but they (its inhabitants) sleep on their beds, and the Holy One Blessed be He brings down rain for them. To teach that not as the ways of flesh and blood are the ways of the Holy One Blessed be He. (A man of) flesh and blood acquires servants to feed and sustain him. But He who spoke and brought the world into being — He acquires servants for Himself, whom He Himself feeds and sustains.
