Charles H. Spurgeon on Psalms 106:33

They provoked his spirit. In a dispensation itself mainly gracious, and foreshadowing one which would be grace altogether, it was of prime importance that the mediating men should be merciful and gracious, long suffering, and slow to anger. And sure they were in marvellous manner. . . . Brimming, over with instruction as is this passage, we must leave it with a few remarks.

1. How careful preachers of the gospel and expounders of Scripture should be not to give an erroneous impression of God's mind or message. The mental acumen is rare, but the right spirit is rarer. But what is the right spirit? —A loving spirit, a gentle spirit, a faithful spirit, a meek and weaned spirit, a spirit which says, "Speak, Lord, for thy servant heareth", and a spirit which adds, "All that the Lord giveth me, that will I speak", that excellent spirit which is only imparted by the good Spirit of God. For if He withdraw, even a Moses ceases to be meek, and ceasing to be meek, even a Moses becomes a bad divine and an erroneous teacher, striking the rock that has been already stricken once for all, and preaching glad tidings gruffly. He who gives the living water does not grudge it; but sometimes, instead of "Ho! every one that thirsteth", the preacher says, "Hear now, ye rebels; must we fetch you water out of this rock?" and makes the very invitation repulsive.

2. When any one has run long and run well, how sad it is to stumble within a few steps of the goal! If Moses had an earthly wish, it was to see Israel safe in their inheritance, and his wish was all but consummated. Faith and patience had held out well nigh forty years, and in a few months more the Jordan would be crossed and the work would be finished. And who can tell but this very nearness of the prize helped to create something of a presumptuous confidence? The blood of Moses was hot to begin with, and he was not the meekest of men when he smote the Egyptian and hid him in the sand. But he had got a good lesson in ruling his spirit, and betwixt the long sojourn with Jethro and the self discipline needful in the charge of this multitude, he might fancy that he had now his foot on the neck of this enemy: when lo! the sin revives and Moses dies.

Blessed is the man that feareth alway! Blessed is the man who, although years have passed without an attempt at burglary, still bars his doors and sees his windows fastened! Blessed is the man who, although a generation has gone since the last eruption, forbears to build on the volcanic soil and dreads fires which have smouldered for fourscore years! Blessed is the man who, even when the high seas are crossed and the land is made, still keeps an outlook! Blessed is the man who, even on the confines of Canaan, takes heed of the evil heart, lest, with a promise of entering in, he should come short through unbelief!
