Psalms 106:37

37.And they sacrificed The prophet here mentions one species of superstition which demonstrates the awful blindness of the people; their not hesitating to sacrifice their sons and daughters to devils. (269) In applying such an abominable designation to the sin of the people, he means to exhibit it in more hateful colors. From this we learn that inconsiderate zeal is a flimsy pretext in favor of any act of devotion. For by how much the Jews were under the influence of burning zeal, by so much does the prophet convict them with being guilty of greater wickedness; because their madness carried them away to such a pitch of enthusiasm, that they did not spare even their own offspring. Were good intentions meritorious, as idolaters suppose, then indeed the laying aside of all natural affection in sacrificing their own children was a deed deserving of the highest praise. But when men act under the impulse of their own capricious humor, the more they occupy themselves with acts of external worship, the more do they increase their guilt. For what difference was there between Abraham and those persons of whom the prophet makes mention, but that the former, under the influence of faith, was ready to offer up his son, while the latter, carried away by the impulse of intemperate zeal, cast off all natural affection, and imbrued their hands in the blood of their own offspring.
