An holy convocation - An assembly called by proclamation for a religious solemnity. See Leviticus 23:2; Numbers 10:2-3. In the East the proclamation is made by the Muezzins from the minarets of the mosques.
Save that ... - In this the observance of the festival differed from the Sabbath, when the preparation of food was prohibited. The same word for “work” is used here and in the fourth commandment: it is very general, and includes all laborious occupation.
