George Haydock's Catholic Commentary
Psalms 120:8
Coming in. Hebrew has, "going out," first. (Berthier) --- Yet Pagnin agrees with us. (Haydock) --- This expression denotes all the occurrences of life, Deuteronomy xxviii. 6. (Calmet) --- We may discover a beautiful progression in this psalm; God protects us from each and from every danger. (Berthier) --- He is not like earthly friends, who have not always the will or the power to do it. (St. Chrysostom)
