Psalms 67:27

From the fountains of Israel. From whom both Christ and his apostles sprung. By Benjamin, the holy Fathers on this place understand St. Paul, who was of that tribe, name here a youth, because he was the last called to the apostleship. By the princes of Juda, Zabulon, and Nephthali, we may understand the other apostles, who were of the tribe of Juda; or of the tribes of Zabulon and Nephthali, where our Lord began to preach, Matthew iv. 13., &c. (Challoner) --- The Jews were first invited, Acts i. (Worthington) --- All the tribes were present at the translation of the ark. It is not known why these four alone are mentioned. (Berthier)
