Exodus 17:2

17:2 So the people contended with Moses, and they said, “Give us water to drink!” Moses said to them, “Why do you contend with me? Why do you test the Lord?”

Exodus 20:20

20:20 Moses said to the people, “Do not fear, for God has come to test you, that the fear of him may be before you so that you do not sin.”

tn The verb וַיָּרֶב (vayyarev) is from the root רִיב (riv); it forms the basis of the name “Meribah.” The word means “strive, quarrel, be in contention” and even “litigation.” A translation “quarrel” does not appear to capture the magnitude of what is being done here. The people have a legal dispute – they are contending with Moses as if bringing a lawsuit.

tn The imperfect tense with the vav (ו) follows the imperative, and so it carries the nuance of the logical sequence, showing purpose or result. This may be expressed in English as “give us water so that we may drink,” but more simply with the English infinitive, “give us water to drink.”

sn One wonders if the people thought that Moses and Aaron had water and were withholding it from the people, or whether Moses was able to get it on demand. The people should have come to Moses to ask him to pray to God for water, but their action led Moses to say that they had challenged God (B. Jacob, Exodus, 476).

tn In this case and in the next clause the imperfect tenses are to be taken as progressive imperfects – the action is in progress.

tn The verb נָסָה (nasah) means “to test, tempt, try, prove.” It can be used of people simply trying to do something that they are not sure of (such as David trying on Saul’s armor), or of God testing people to see if they will obey (as in testing Abraham, Gen 22:1), or of people challenging others (as in the Queen of Sheba coming to test Solomon), and of the people in the desert in rebellion putting God to the test. By doubting that God was truly in their midst, and demanding that he demonstrate his presence, they tested him to see if he would act. There are times when “proving” God is correct and required, but that is done by faith (as with Gideon); when it is done out of unbelief, then it is an act of disloyalty.

tn נַסּוֹת (nassot) is the Piel infinitive construct; it forms the purpose of God’s coming with all the accompanying phenomena. The verb can mean “to try, test, prove.” The sense of “prove” fits this context best because the terrifying phenomena were intended to put the fear of God in their hearts so that they would obey. In other words, God was inspiring them to obey, not simply testing to see if they would.

tn The suffix on the noun is an objective genitive, referring to the fear that the people would have of God (GKC 439 §135.m).

tn The negative form לְבִלְתִּי (lÿvilti) is used here with the imperfect tense (see for other examples GKC 483 §152.x). This gives the imperfect the nuance of a final imperfect: that you might not sin. Others: to keep you from sin.
