George Haydock's Catholic Commentary
Psalms 77:31
Israel. St. Jerome applies this to those who receive unworthily, particularly if they be priests, 1 Corinthians xi. 29. (Calmet) --- God selected the most guilty (Berthier) having allowed them to feast for a whole month. (Worthington) --- Then he brought down by death, or "hindered," as it were, "by shackles," (Septuagint) the most valiant. (Haydock)
