John Calvin's Bible Commentary
Psalms 9:12
12.For in requiring blood. In the original, it is bloods, in the plural number, and, therefore, the relative which follows immediately after, And remembereth THEM, may very properly be referred to that word in this way, He requireth bloods, and remembereth them. But as it is sufficiently common in Hebrew to invert the order of the antecedent and the relative, and to put them before the word to which it refers, (176) some explain it of the poor, thus: In requiring blood, he hath remembered them, namely, the poor, of whom he speaks a little after. As to the sum and substance of the matter, it is of small importance in which of these ways we explain the relative; but the former is, in my view, the more natural explanation. There is here a repetition of what the Psalmist had said a little before, that we ought especially to consider God’s power, as it is manifested in the mercy which he exercises towards his servants, who are unrighteously persecuted by wicked men. From the numerous works of God, he selects one which he commends as especially worthy of being remembered, namely, his work in delivering the poor from death. God sometimes leaves them in his holy providence to be persecuted by men; but at length he takes vengeance for the wrongs inflicted upon them. The words which David uses denote a continued act; but I have no doubt that he intends from those examples, which he has related in the preceding part of the psalm, to lead men to acknowledge that God requireth innocent blood, and remembers the cry of his people.
He again insists on what I adverted to before, that God does not always put a stop to injuries so speedily as we would wish, nor break the attempts of the wicked at the first, but rather withholds and delays his assistance, so that it may seem that we cry to him in vain, a truth which it is of importance for us to understand; for if we measure the help of God according to our senses, our courage will ever and anon fail us, and in the end our hope will be entirely extinguished, and will give place to despondency and despair. We would fondly wish him, as I have said, to stretch forth his hand to a distance, and drive back the troubles which he sees to be prepared for us; yet he seems to take no notice, and does not prevent the blood of the innocent from being shed. Let this consolatory consideration, however, sustain us, that he will at length actually show how precious our blood was in his sight. If it is objected, that God’s assistance comes too late, after we have endured all calamities, I answer, God delays to interfere no longer than he knows it to be of advantage for us to be humbled under the cross, and if he chooses rather to take vengeance after we have suffered outrage, than to aid us previous to the infliction of evil, it is not because he is not always willing and ready to succor us; but because he knows it is not always a proper time for manifesting his grace. By the way, it is a striking evidence, not only of his fatherly love towards us, but of the blessed immortality which is the portion of all the children of God, that he has a care about them even after they are dead. Were he always by his grace to prevent affliction from befalling us, who is there amongst us who would not be wholly attached to the present life? When, however, he avenges our death, from this it appears that, though dead, we still remain alive in his presence. For he does not, after the manner of men, hold in estimation the memory of those whom he could not preserve alive, (177) but he actually shows that he cherishes in his bosom, and gives protection to those who seem to be no more, viewing them according to the flesh. And this is the reason why David says that he remembereth blood when he requireth it; for although he may not presently deliver his servants from the swords of the wicked, yet he suffers not their murder to pass unpunished. To the same purpose is the last clause He forgetteth not the cry of the afflicted God may not show, by granting instant deliverance or relief, that he lends an immediate ear to the complaints of his servants; but at length he proves unanswerably that he has regarded them. Express mention is made of crying, to encourage all who desire to experience God as their deliverer and protector, to direct their wishes, groanings, and prayers to him.
