Wherefore the people did chide with Moses. Here now displays itself both their impiety against God, since neglecting and despising Him they make war against Moses, and also their malice and unkindness, because, forgetful of so many benefits, they wantonly insult Moses. They know that fountains and rivers cannot be created by mortal man; wherefore, then, do they quarrel with him, and not call directly upon God, in whose hand are the waters as well as all other elements? Certainly, if there had been a spark of faith in them, they would have had recourse to prayer. Rightly, then, does Moses expostulate, that in chiding with him, they tempt God Himself. What madness is there in their accusing Moses of cruelty in bringing them with him out of Egypt, that he might kill them, and their children, and cattle in the wilderness? But Moses chiefly reproves them on this ground, because God Himself is affected by this rebellious chiding. But the actual form of their tempting God is stated at the end, viz., because they had doubted "whether the Lord was among them or not?" Hence it follows, that the root of the whole evil was their unbelief; because they neither ascribed due honor to God's power nor believed Him to be true to his promises.: For He had taken charge of them, and had promised that He would never fail them; why then, now, when circumstances demand it, do they not assure themselves that He will assist them, except because they wickedly detract both from His power and His truth?

Tempt the Lord - It is a general characteristic of the Israelites that the miracles, which met each need as it arose, failed to produce a habit of faith: but the severity of the trial, the faintness and anguish of thirst in the burning desert, must not be overlooked in appreciating their conduct.

Why chide ye with me? - God is your leader, complain to him; Wherefore do ye tempt the Lord? As he is your leader, all your murmurings against me he considers as directed against himself; why therefore do ye tempt him? Has he not given you sufficient proofs that he can destroy his enemies and support his friends? And is he not among you to do you good? Exodus 17:7. Why therefore do ye doubt his power and goodness, and thus provoke him to treat you as his enemies?

Wherefore the people did chide with Moses, and said, Give us water that we may drink. And Moses said unto them, Why chide ye with me? wherefore do ye (b) tempt the LORD?
(b) Why do you distrust God? Why do you not look for comfort from him without complaining to us?

Wherefore the people did chide with Moses,.... Contended with him by words, expostulating with him in a very angry and indecent manner for bringing them thither; loading him with reproaches and calumnies, wrangling and quarrelling with him, and using him very ill, giving hard words and bad language:
and said, give us water, that we may drink; directing their speech both to Moses and Aaron, as the word "give" (g) being in the plural number shows; which was requiring that of them which only God could do and signifying as if they were under obligation to do it for them, since they had brought them out of Egypt, and had the care of them; and having seen so many miracles wrought by them, might conclude it was in their power to get them water when they pleased: had they desired them to pray to God for them, to give them water, and exercised faith on him, that he would provide for them, they had done well; which they might reasonably conclude he would, who had brought them out of Egypt, led them through the Red sea, had sweetened the waters at Marah for them, conducted them to fountains of water at Elim, and had rained flesh and bread about their tents in the wilderness of Sin, and still continued the manna with them:
and Moses said unto them, why chide ye with me? as if it was I that brought you hither, whereas it is the Lord that goes before you in the pillar of cloud and fire, and as if I kept water from you, or could give it you at pleasure; how unreasonable, as well as how ungenerous is it in you to chide with me on this account
wherefore do you tempt the Lord? the Lord Christ, as appears from 1-Corinthians 10:9 who with the Father and Spirit is the one Jehovah; him they tempted or tried; they tried whether he was present with them or not, Exodus 17:7, they tried his power, whether he could give them water in a dry and desert land; and they tried his patience by chiding with his servants, and showing so much distrust of his power and providence, of his goodness and faithfulness; and by their wretched ingratitude and rebellion they tempted him to work a miracle for them.

the people did chide with Moses, and said, Give us water that we may drink, &c.--The want of water was a privation, the severity of which we cannot estimate, and it was a great trial to the Israelites, but their conduct on this new occasion was outrageous; it amounted even to "a tempting of the Lord." It was an opposition to His minister, a distrust of His care, an indifference to His kindness, an unbelief in His providence, a trying of His patience and fatherly forbearance.
