22 Then Moses took Israel forward from the Red Sea, and they went out into the waste land of Shur; and for three days they were in the waste land where there was no water. 23 And when they came to Marah, the water was no good for drinking, for the waters of Marah were bitter, which is why it was named Marah. 24 And the people, crying out against Moses, said, What are we to have for drink? 25 And in answer to his prayer, the Lord made him see a tree, and when he put it into the water, the water was made sweet. There he gave them a law and an order, testing them; 26 And he said, If with all your heart you will give attention to the voice of the Lord your God, and do what is right in his eyes, giving ear to his orders and keeping his laws, I will not put on you any of the diseases which I put on the Egyptians: for I am the Lord your life-giver. 27 And they came to Elim where there were twelve water-springs and seventy palm-trees: and they put up their tents there by the waters.

(Read Exodus 15:22-27)
In the wilderness of Shur the Israelites had no water. At Marah they had water, but it was bitter; so that they could not drink it. God can make bitter to us that from which we promise ourselves most, and often does so in the wilderness of this world, that our wants, and disappointments in the creature, may drive us to the Creator, in whose favour alone true comfort is to be had. In this distress the people fretted, and quarrelled with Moses. Hypocrites may show high affections, and appear earnest in religious exercises, but in the time of temptation they fall away. Even true believers, in seasons of sharp trial, will be tempted to fret, distrust, and murmur. But in every trial we should cast our care upon the Lord, and pour out our hearts before him. We shall then find that a submissive will, a peaceful conscience, and the comforts of the Holy Ghost, will render the bitterest trial tolerable, yea, pleasant. Moses did what the people had neglected to do; he cried unto the Lord. And God provided graciously for them. He directed Moses to a tree which he cast into the waters, when, at once, they were made sweet. Some make this tree typical of the cross of Christ, which sweetens the bitter waters of affliction to all the faithful, and enables them to rejoice in tribulation. But a rebellious Israelite shall fare no better than a rebellious Egyptian. The threatening is implied only, the promise is expressed. God is the great Physician. If we are kept well, it is he that keeps us; if we are made well, it is he that recovers us. He is our life and the length of our days. Let us not forget that we are kept from destruction, and delivered from our enemies, to be the Lord's servants. At Elim they had good water, and enough of it. Though God may, for a time, order his people to encamp by the bitter waters of Marah, that shall not always be their lot. Let us not faint at tribulations.
