Hosanna

The general opinion is that of St. Jerome, that the word originated from two Hebrew words of Psalm cxvii (cxviii), 25. This psalm, was recited by one of the priests every day during the procession round the altar, during the Feast of Tabernacles, when the people were commanded to "rejoice before the Lord" (Lev., xxiii, 40); and on the seventh day it was recited each time during the seven processions.
