(8) In the day of temptation.--Better, like the day of the temptation. As in the LXX., so here, two words which in the Hebrew are proper names ("as at Meribah, and as in the day of Massah") are translated according to their intrinsic meaning. (For the former see Exodus 17:7; Numbers 20:13; and for the latter Exodus 17:7.) We may believe that these places are here chosen for reference partly on account of their significant names; but it is noteworthy that the rebellions recorded in the names belonged to the beginning and to the close of the years of wandering.

3:7-13 Days of temptation are often days of provocation. But to provoke God, when he is letting us see that we entirely depend and live upon him, is a provocation indeed. The hardening of the heart is the spring of all other sins. The sins of others, especially of our relations, should be warnings to us. All sin, especially sin committed by God's professing, privileged people, not only provokes God, but it grieves him. God is loth to destroy any in, or for their sin; he waits long to be gracious to them. But sin, long persisted in, will make God's wrath discover itself in destroying the impenitent; there is no resting under the wrath of God. Take heed: all who would get safe to heaven must look about them; if once we allow ourselves to distrust God, we may soon desert him. Let those that think they stand, take heed lest they fall. Since to-morrow is not ours, we must make the best improvement of this day. And there are none, even the strongest of the flock, who do not need help of other Christians. Neither are there any so low and despised, but the care of their standing in the faith, and of their safety, belongs to all. Sin has so many ways and colours, that we need more eyes than ours own. Sin appears fair, but is vile; it appears pleasant, but is destructive; it promises much, but performs nothing. The deceitfulness of sin hardens the soul; one sin allowed makes way for another; and every act of sin confirms the habit. Let every one beware of sin.Harden not you hearts,.... There is a natural hardness of the heart; the heart of man is like a stone, destitute of spiritual life, motion, and activity; it is senseless, stupid, impenitent, stubborn, and inflexible, on which no impressions can be made, but by powerful grace: and there is an acquired, habitual, and voluntary hardness of heart, to which men arrive by various steps; as entertaining pleasing thoughts of sin; an actual commission of it, with frequency, till it becomes customary, and so habitual; an extenuation or justification of it, and so they become hardened against all reproofs and sermons, and to all afflictions and judgments; are insensible and past feeling, and openly declare for sin, and glory in it: and there is a hardness which God's people are liable to, and should guard against; and which is brought on by a neglect of private and public worship, and by keeping bad company, and through the ill examples of others, and by giving way to lesser sins; for all sin is of an hardening nature:

as in the provocation, in the day of temptation in the wilderness; the Jews provoked God in the wilderness by their unbelief, murmurings, ingratitude, and idolatry; and they tempted him there by distrusting his power and goodness; hence one of the places in which they murmured against him was called Massah and Meribah, Exodus 17:7 and it is an aggravation of their sin, that it was in the wilderness, after they had been just brought out of bondage into liberty, and had lately had such an instance of the power and goodness of God, in bringing them through the Red sea; and where they could have no human supplies, and therefore should have been entirely dependent on God, and trust in him.
