22 Moses led Israel from the Red Sea on to the Wilderness of Shur. They traveled for three days through the wilderness without finding any water. 23 They got to Marah, but they couldn't drink the water at Marah; it was bitter. That's why they called the place Marah (Bitter). 24 And the people complained to Moses, "So what are we supposed to drink?" 25 So Moses cried out in prayer to God. God pointed him to a stick of wood. Moses threw it into the water and the water turned sweet. 26 That's the place where God set up rules and procedures; that's where he started testing them. God said, "If you listen, listen obediently to how God tells you to live in his presence, obeying his commandments and keeping all his laws, then I won't strike you with all the diseases that I inflicted on the Egyptians; I am God your healer." 27 They came to Elim where there were twelve springs of water and seventy palm trees. They set up camp there by the water.

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.
