Relieved as they were of all the cares of subsistence through the gift of manna, it was plainly the duty of the Israelites to devote themselves exclusively to the study of the Torah. When, therefore, they slackened in the performance of this duty, punishment in the form of lack of water immediately overtook them. This was the first time that they actually experienced this want, for at Marah nothing more than alarm that this need might come upon them, had caused them to murmur and complain.
In their distress they once more unreasonably cast reproaches upon their leader, and disputed with him, saying: "Wherefore is this, children, that thou hast brought us up out of Egypt, to kill us, and our children, and our cattle with thirst?" Moses replied: "As often as you quarrel with me, you tempt God, but God performeth wonders and excellent deeds for you, as often as you dispute with me, that His name may sound in glory throughout the world."
