George Haydock's Catholic Commentary
Psalms 101:24
He answered him in the way of his strength. That is, the people mentioned in the foregoing verse, or the penitent, in whose person this psalm is delivered, answered the Lord in the way of his strength: that is, according to the best of his power and strength; inquiring after the fewness of his days: to know if he should live long enough to see the happy restoration of Sion, &c. (Challoner) --- The sense of the Vulgate is as good as that of the present Hebrew, "he hat weakened (afflicted; Montanus) my strength, in the way; He hath shortened my days. I said, my God, make me not depart in the midst," &c. --- The captives, or those who were set free, address God, though the psalmist himself may express what prayers he had poured forth in his bonds. (Calmet) --- The variation of the Septuagint and Hebrew originates in the points; and the text has, his force, very properly, though the Jews would substitute "my." (Berthier) --- The stability of the Church is hence proved by St. Augustine. (Haydock)
