Let the sighing of the prisoner come before thee - The sighing of him who is bound. The allusion here is, doubtless, to those among the Hebrews who had been taken captives, and who “sighed” not only on account of the sufferings which they endured in their bondage, but because they had been taken from their country and home. The meaning is, “Hear those sighs, and come for the deliverance of those who are thus held in captivity.”
According to the greatness of thy power - Margin, as in Hebrew, thine arm. The arm is the symbol of power. It is implied here that great power was needful to deliver those who were held in captivity, power such as God only could exert - power which could be wielded only by an Omnipotent Being. It was the power of God only which could rescue them, as it is only by the power of God that sinners can be saved.
Preserve thou those that are appointed to die - Margin, Reserve the children of death. The literal meaning is, “Let remain the sons of death;” that is, Preserve those who are in such circumstances that death is impending, and who may be called the sons of death. This might apply to those who were condemned to death; or, to those who were sick and in danger of death; or to those who were prisoners and captives, and who were, by their sufferings, exposed to death. The prayer is that such might be suffered to remain on the earth; that is, that they might be kept alive.
