Leviticus 23:1-3

The Sabbath, which is to be kept holy, i.e. unprofaned by any kind of work for individual profit, and marked by a religious gathering, apparently at a synagogue. The term set feast (RV) means an assembly. The same word is used in the name for the shrine, the tent of meeting. The older name for these feasts was hag, properly a pilgrimage; this term, however, would not apply to the Sabbath.
