Water is one of the things most essential to life. Indeed, it is life. It constitutes two-thirds of the human body. Without a proper supply of water, both animals and plants soon cease to exist. Those people in the desert would soon have perished, if water had not been provided for them. It was therefore life to them. Everybody who has suffered from thirst can vividly realize how the spirits of the children of Israel revived, and new life sprang up in them, as they drank of that fresh, sparkling living water that gushed forth from the smitten rock.
