Psalms 131:9

Justice. And all virtues, (Berthier) of which their robes were emblematical. --- Saints. Levites. (Chaldean) (Calmet) --- Let both priests and Levites perform well their sacred functions, (Worthington) and may all the faithful act up to their vocation. (Berthier) --- Rejoice. Hebrew, "sing," which was the office of the Levites. (Calmet) --- Yet the original term is more comprehensive, and denotes all the emotions of joy. (Haydock)
