George Haydock's Catholic Commentary
Psalms 9:38
or Hebrew Psalm x. Ver. 17. The. Hebrew, "Thou, Lord, hast heard the desire of the humble. Thou wilt prepare their heart; thou wilt cause thine ear to hear." (Protestants; Haydock) --- Luther seems to have altered the text in his German version, in order to establish his error of the certitude of salvation; "their heart is sure that thine ear hath heard." The Hebrew intimates that God prepares the heart for all good. (Berthier) --- He hears before his servants cry out, (Isaias lxv. 24.) since his spirit inspires the petitions, Romans viii. 26., and Galatians iv. 6. (Calmet) --- The cry of the heart is charity, amore petitur. (St. Augustine, Mor. Ecc.) --- The just man is always ready to suffer whatever God may appoint. (Worthington)
