So Moses brought Israel from the Red sea, and they went out into the wilderness of Shur; and they went three days in the wilderness…
Consider that murmuring is a mercy-embittering sin, a mercy-souring sin. As the sweetest things put into a sour vessel are soured, or put into a bitter vessel are embittered; so murmuring puts gall and wormwood into every cup of mercy that God gives into our hands. The murmurer writes "Marah," that is, bitterness, upon all his mercies, and he reads and tastes bitterness in them all. As "to the hungry soul every bitter thing is sweet," so to the murmuring soul every sweet thing is bitter.
