Numbers 20:12

The Lord then said to both of them, both Moses and Aaron, "Because ye have not trusted firmly in Me, to sanctify Me before the eyes of the children of Israel, therefore ye shall not bring this congregation into the land which I have given them." The want of belief or firm confidence in the Lord, through which both of them had sinned, was not actual unbelief or distrust in the omnipotence and grace of God, as if God could not relieve the want of water or extend His help to the murmuring people; for the Lord had promised His help to Moses, and Moses did what the Lord had commanded him. It was simply the want of full believing confidence, a momentary wavering of that immovable assurance, which the two heads of the nation ought to have shown to the congregation, but did not show. Moses did even more than God had commanded him. Instead of speaking to the rock with the rod of God in his hand, as God directed him, he spoke to the congregation, and in these inconsiderate words, "Shall we fetch you water out of the rock?" words which, if they did not express any doubt in the help of the Lord, were certainly fitted to strengthen the people in their unbelief, and are therefore described in Psa 106:33 as prating (speaking unadvisedly) with the lips (cf. Lev 5:4). He then struck the rock twice with the rod, "as if it depended upon human exertion, and not upon the power of God alone," or as if the promise of God "would not have been fulfilled without all the smiting on his part" (Knobel). In the ill-will expressed in these words the weakness of faith was manifested, by which the faithful servant of God, worn out with the numerous temptations, allowed himself to be overcome, so that he stumbled, and did not sanctify the Lord before the eyes of the people, as he ought to have done.

At this chapter begins the history of the fortieth year (which was the last year) of the Israelites' wandering in the wilderness. And since the beginning of their second year, when they were sentenced to perform their quarantine in the desert, there to wear away the tedious revolution of forty years, there is little recorded concerning them till this last year, which brought them to the borders of Canaan, and the history of this year is almost as large as the history of the first year. This chapter gives an account of, I. The death of Miriam (Num 20:1). II. The fetching of water out of the rock, in which observe, 1. The distress Israel was in, for want of water (Num 20:2). 2. Their discontent and murmuring in that distress (Num 20:3-5). 3. God's pity and power engaged for their supply with water out of the rock (Num 20:6-9). 4. The infirmity of Moses and Aaron upon this occasion (Num 20:10, Num 20:11). 5. God's displeasure against them (Num 20:12, Num 20:13). III. The negotiation with the Edomites. Israel's request (Num 20:14-17), and the repulse the Edomites gave them (Num 20:18-21). IV. The death of Aaron the high priest upon Mount Hor, the instalment of Eleazar in his room, and the people's mourning for him (Num 20:22, etc.).
