3:8 Harden not your hearts, as in the {g} provocation, in the day of temptation in the wilderness:
(g) In the day that they troubled the Lord, or struggled with him.
3:8 Harden not your hearts. To harden the heart is to reach such a state that God's voice makes no impression.
As in the provocation. The Hebrew of the Psalm says Like Meribah. The meaning is Harden not your hearts as our fathers did at Meribah. See the account in Ex 17:1-7. See also Nu 27:14, where Kadesh Meribah is named. Both may be referred to.
In the day of temptation in the wilderness. Day of trial.
3:8 As in the provocation - When Israel provoked me by their strife and murmurings. In the day of temptation - When at the same time they tempted me, by distrusting my power and goodness. Exod 17:7.
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.
