What profit [is there] in my blood?.... Should that be shed, and he die by the hands of his enemies, through divine permission: death is not profitable to a man's self by way of merit; it does not atone for sin, satisfy justice, and merit heaven; even the death of martyrs, and of such who shed their blood, died in the cause of Christ, and for his sake, is not meritorious; it does not profit in such sense: there is profit in no blood but in the blood of Christ, by which peace is made, pardon procured, and redemption obtained.
Indeed death is consequentially profitable to good men; it is an outlet of all sorrows and afflictions, and the inlet of joy and happiness; it is the saints' passage to heaven, and upon it they are immediately with Christ, and rest from their labours: nor is there profit in the blood of the saints to them that shed it; for when inquisition is made for it, vengeance will be taken on them who have shed it, and blood will be given them to drink, as will be particularly to antichrist: nor is there any profit in it to the Lord himself; which seems to be what is chiefly designed, since it is used by the psalmist as an argument with him in prayer, that he might not be left by him, and to his enemies, so as to perish, since no glory could accrue to God by it from them; they would not give him thanks for it, but ascribe it to themselves, and say their own hand had done it; so far, the psalmist suggests, would his death be from being profitable to God, that it would rather be a loss to the interest of religion; since he had not as yet fully restored religion, and settled the pure worship of God in order, and made the preparations for the building the house of God he intended.
