Sailhamer: His instruction would be sweet to them and satisfy their thirst.



V. The Wilderness Wanderings (15:22-18:27)

A. God's Provision for Israel in the Desert (15:22-27)
After the destruction of the pharaoh's army in the sea, the Israelites continued their journey eastward into the Desert of Shur. Shur was a large semi-desert region east of the Egyptian border frontier. After three days without finding water, they arrived at Marah. There the Lord began to provide for the people, and the people learned to depend on his provision.

There is an important narrative lesson in the incident of the bitter waters. When the people were helpless and thirsty, Moses called out to the Lord for help. The Lord answered Moses by giving him an “instruction” on how to make the water sweet. When they followed the “instruction,” the water became sweet and their thirst was satisfied (v.25). In the Hebrew text, the word “instruction” means divine instruction. There is then a lesson about God's instructions to Israel in this incident: God's people must “listen carefully to the voice of the LORD [their] God” (v.26). His instruction would be sweet to them and satisfy their thirst.

The mention of “a decree and a law” (v.25b) for Israel and of Israel's being called upon to listen to the Lord's “commands” and “decrees” before the time of the giving of the Law at Sinai raises many questions. Already at this stage in their journey God had made known his will to the Israelites in concrete laws, such as the commands for keeping the Sabbath and those necessary for the administration of justice. We may posit a distinction between God's initial giving of the law to Israel, which was not too burdensome to bear, and God's giving of the detailed laws at Sinai after the incident of the Golden Calf (ch. 32). The Law was originally intended to teach God's people what was “right in his eyes” (15:26). After the failure of the people in the incident of the golden calf, however, more stringent measures were taken to keep the people from falling away into idolatry. Paul appears to have this view of the secondary nature of the Mosaic law in Gal 3:19, where he says that the Mosaic law “was added because of the transgressions.”

Having learned the lesson of dependence on God and listening to his voice, the people moved on to Elim where they found abundant water and nourishment (15:27).

John Stott on the "old man" and the "body ruled by sin" in Rom 6 v 6

  There are, in fact, two quite distinct ways in which the New Testament speaks of crucifixion in relation to holiness. The first is our death to sin through identification with Christ; the second is our death to self through imitation of Christ.  On the one hand, we have been crucified with Christ. But on the other we have crucified (decisively repudiated) our sinful nature with all its desires, so that every day we renew this attitude by taking up our cross and following Christ to crucifixion.  The first is a legal death, a death to the penalty of sin; the second is a moral death, a death to the power of sin.  The first belongs to the past, and is unique and unrepeatable; the second belongs to the present, and is repeatable, even continuous. I died to sin (in Christ) once; I die to self (like Christ) daily. It is with the first of these two deaths that Romans 6 is chiefly concerned, although the first is with a view to the second, and the second cannot take place w...

Berkoff: "The law was not substituted for the promise; neither was faith supplanted by works. "

  The giving of the law did not effect a fundamental change in the religion of Israel, but merely introduced a change in its external form.  The law was not substituted for the promise; neither was faith supplanted by works.  Many of the Israelites, indeed, looked upon the law in a purely legalistic spirit and sought to base their claim to salvation on a scrupulous fulfillment of it as a body of external precepts.  But in the case of those who understood its real nature, who felt the inwardness and spirituality of the law, it served to deepen the sense of sin and to sharpen the conviction that salvation could be expected only from the grace of God .

F.F. Bruce: ...know their father's will...

The NT does not contain a detailed code of rules for the Christian. Codes of rules, as Paul explains elsewhere, are suited to the period of immaturity when the children of God are still under guardians; but children who have come to years of responsibility know their father’s will without having to be provided with a long list of “Do’s” and “Don’t’s.” What the NT does provide is those basic principles of Christian living which may be applied to varying situations of life as they arise. So, after answering the Corinthian Christians’ question about the eating of food that has been offered to idols, Paul sums up his advice in the words: “whether you eat or drink, or whatever you do, do all to the glory of God” (1 Cor. 10:31). Phrases current in worship, like “to the glory of God” or (as here) “in the name of the Lord Jesus,” were given a practical relevance by being applied to the concerns of ordinary life. Bruce, F. F. (1984). The Epistles to the Colossians, to Philemon, and to the...
