John Gill Bible Commentary

Let the sighing of the prisoner come before thee,.... Such as were so in a literal or spiritual sense; and the sighs and groans of such are not hid from the Lord; they come up into his ears as did the sighing and groaning of the children of Israel when in Egypt, Exo 2:23, according to the greatness of thy power, preserve thou those that are appointed to die; not by the Lord, as all men are, but by men; who are under a sentence of condemnation, who are ready to die, being appointed to destruction, Pro 31:6, or are in danger of death, as Jarchi observes; the phrase is used in Talmudic writings; whose lives are exposed to danger, who are killed all the day long, and are accounted as sheep for the slaughter, Psa 44:22, these it is desired the Lord would keep from dying, or cause them to remain in life; or not suffer their lives to be taken away from them, which he was able to do through "the greatness of his power"; though these words according to the accents belong to the preceding clause. The Targum, and so Jarchi, and other Jewish writers, render the words, "loose thou those", &c. mention being made before of prisoners, or of persons bound.
