Augustine of Hippo
Let the cries of those imprisoned come before Your sight. It is difficult for anyone to grasp that the righteous were bound by their oppressors; even when such instances occur amid immense suffering, they are rare, leading one to wonder why the prophet chose to highlight this in his verse. In truth, the true chains are the frailty and decay of the body, which burden the spirit. Through this frailty, a tool for various pains and trials, the adversary could sway the soul toward wickedness. The Apostle longed to be liberated from these chains and to dwell with Christ, yet he acknowledged the necessity of remaining in the flesh for the sake of those to whom he preached the Gospel.

Until this corruptible body puts on incorruption, and this mortal being steps into immortality, the weak flesh can release the willing spirit. As noted in Matthew 26:41, it is in this state that no one feels the weight of their chains, yet they groan within themselves, burdened, yearning to don the heavenly dwelling because both death brings fear and mortal life is filled with sorrow. For the sake of those who groan, the prophet intensifies his own lamentations, so their cries may be presented to the Lord. Those who are bound by the principles of wisdom, which, when endured patiently, become adornments, can also be seen as shackled; hence it is stated, "Put your feet into her fetters" (Sirach 6:24). According to the magnitude of Your strength, may You welcome the children of those who perish, or as some lists suggest, bring forth children from the deaths of the chastened. In these verses, Scripture clearly indicates the lament of those constrained, who, in the name of Christ, faced terrible tribulations, prophesied throughout this psalm. Enduring diverse afflictions, they prayed for the Church, that their sacrifices would not be in vain for future generations, allowing the Lord's harvest to flourish more abundantly, even as their foes believed it would fall to ruin. The “sons of the slain” refer to those who were not daunted by the sufferings of their predecessors; rather, inspired by the glory of their sacrifices for Christ's name, they were ignited to act boldly in the faith of the multitude. Thus, the phrase "According to the greatness of Your strength" signifies the profound miracle that befell the Christian nations, as they overcame great obstacles, and even the wise among them could not foresee what would ensue.
