George Haydock's Catholic Commentary
Psalms 67:32
Ambassadors shall come, &c. It is a prophecy of the conversion of the Gentiles, and by name of the Egyptians and Ethiopians, (Challoner) who were among the first converts, Isaias xix 9., Sophonias iii. 10., and Acts viii. 27. --- Ambassadors. Hebrew chashmannim occurs no where else. But it denotes some people in authority, and seems to have the same import as "the Asmonean." --- Ethiopia, comprises the country on both sides of the Red Sea, as well as that below Egypt, and on the Araxes. This prediction was accomplished, when Solomon married the daughter of Pharao, and was visited by the queen of Saba. But is was more fully verified by the propagation of the gospel, (Calmet) when many in Egypt became monks and nuns. (Worthington)
