John Calvin's Bible Commentary
Psalms 95:8
8.Harden not your heart, as in Meribah The Psalmist, having extolled and commended the kindness of God their Shepherd, takes occasion, as they were stiffnecked and disobedient, to remind them of their duty, as his flock, which was to yield a pliable and meek submission; and the more to impress their minds, he upbraids them with the obstinacy of their fathers. The term מריבה , Meribah, may be used appellatively to mean strife or contention; but as the Psalmist evidently refers to the history contained in Exodus 17:2, (58) I have preferred understanding it of the place — and so of מסה , Massah. (59) In the second clause, however, the place where the temptation happened may be thought sufficiently described under the term wilderness, and should any read, according to the day of temptation (instead of Massah)in the wilderness, there can be no objection. Some would have it, that Massah and Meribah were two distinct places, but I see no ground to think so; and, in a matter of so little importance, we should not be too nice or curious. He enlarges in several expressions upon the hardness of heart evinced by the people, and, to produce the greater effect, introduces God himself as speaking. (60) By hardness of heart, he no doubt means, any kind of contempt shown to the word of God, though there are many different kinds of it. We find that when proclaimed, it is heard by some in a cold and slighting manner; that some fastidiously put it away from them after they had received it; that others proudly reject it; while again there are men who openly vent their rage against it with despite and blasphemy. (61) The Psalmist, in the one term which he has employed, comprehends all these defaulters, the careless — the fastidious — such as deride the word, and such as are actuated in their opposition to it by frenzy and passion. Before the heart can be judged soft and pliable to the hearing of God’s word, it is necessary that we receive it with reverence, and with a disposition to obey it. If it carry no authority and weight with it, we show that we regard him as no more than a mere man like ourselves; and here lies the hardness of our hearts, whatever may be the cause of it, whether simply carelessness, or pride, or rebellion. He has intentionally singled out the odious term here employed, to let us know what an execrable thing contempt of God’s word is; as, in the Law, adultery is used to denote all kinds of fornication and uncleanness, and murder all kinds of violence, and injury, hatreds, and enmities. Accordingly, the man who simply treats the word of God with neglect, and fails to obey it, is said here to have a hard and stony heart, although he may not be an open despiser. The attempt is ridiculous which the Papists have made to found upon this passage their favorite doctrine of the liberty of the will. We are to notice, in the first place, that all men’s hearts are naturally hard and stony; for Scripture does not speak of this as a disease peculiar to a few, but characteristic in general of all mankind, (Ezekiel 36:26.) It is an inbred pravity; still it is voluntary; we are not insensible in the same manner that stones are, (62) and the man who will not suffer himself to be ruled by God’s word, makes that heart, which was hard before, harder still, and is convinced as to his own sense and feeling of obstinacy. The consequence by no means follows from this, that softness of heart — a heart flexible indifferently in either direction, is at our command. (63) The will of man, through natural corruption, is wholly bent to evil; or, to speak more properly, is carried headlong into the commission of it. And yet every man, who disobeys God therein, hardens himself; for the blame of his wrong doing rests with none but himself.
