When he avenges blood, he remembers them: he forgets not the cry of the humble.
Read Chapter 9
Augustine of Hippo
13. "For requiring their blood He hath remembered" (ver. 12). As if they, who were sent to preach the Gospel, should make answer to that injunction which has been mentioned, "Show forth His wonders among the heathen," and should say, "O Lord, who hath believed our report?" and again, "For Thy sake we are killed all the day long ;" the Psalmist suitably goes on to say, That Christians not without great reward of eternity will die in persecution, "for requiring their blood He hath remembered." But why did he choose to say, "their blood"? Was it, as if one of imperfect knowledge and less faith should ask, How will they "show them forth," seeing that the infidelity of the heathen will rage against them; and he should be answered, "For requiring their blood He hath remembered," that is, the last judgment will come, in which both the glory of the slain and the punishment of the slayers shall be made manifest? But let no one suppose "He hath remembered"to be so used, as though forgetfulness can attach to God; but since the judgment will be after a long interval, it is used in accordance with the feeling of weak men, who think God hath forgotten, because He doth not act so speedily as they wish. To such is said what follows also, "He hath not forgotten the cry of the poor:" that is, He hath not, as you suppose, forgotten. As if they should on hearing, "He hath remembered," say, Then He had forgotten; No, "He hath not forgotten," says the Psalmist, "the cry of the poor."
