George Haydock's Catholic Commentary
Psalms 54:9
PSALM LIV. (EXAUDI DEUS.)
A prayer of a just man under persecution from the wicked. It agrees to Christ persecuted by the Jews, and betrayed by Judas.
Storm. The first fury of the rebels, which is most dangerous, is thus specified. David was convinced, that his son's party would dwindle away, when he was informed that he did not pursue him, following the advice of Chusai. (Calmet) --- Hebrew, "I would hasten my escape from the impetuous wind and tempest." But the Septuagint may be equally correct. (Berthier) --- God protected his weak servant in the greatest dangers. (Worthington)
