With the Hebrews the actual observance of Saturday--the Sabbath--as a day rest, seems to be of pretty late origin. The first mention of it in authentic Hebrew history, as actually observed, occurs about two hundred years after Samuel, and about six hundred after Moses--a little less than nine hundred before Christ. The passage is found in 2 Kings 4: 23; a child had died, as the narrative relates--the mother wished to send for Elisha, "the man of God." Her husband objects, saying, "Wherefore wilt thou go to him to-day? it is neither new moon nor Sabbath." This connection with the new moon is significant. In the earlier historical books of Joshua, Judges, the two books of Samuel, and the first of Kings, there is no mention of the Sabbath, not the least allusion to it. This seems to have been the origin of its observance:--The worship of one God, with the distinctive name Jehovah, gradually got established in the Hebrew nation; for this they seem largely indebted to Moses. Gradually this worship of Jehovah became connected with a body of priests, who were regularly organized at length, and claimed descent from Levi--some of them from Aaron, his celebrated descendant, the elder brother of Moses. The rise of the Levitical priesthood is remarkable, and easily traced in the Old Testament. Some books are entirely destitute of a Levitical spirit, such as Genesis and Judges; others are filled with it, as Leviticus, Deuteronomy, and the books of Chronicles. With the priesthood it seems there came the observance of certain days for religious or festal purposes--New Moon days, Full Moon days, and the like. These seem to have been derived from the nations about them, with whom the moon--deified as Astarte, the Queen and Mother of Heaven, and under other names--was long an object of worship. The observance of those days points back to the period when Fetichism, the worship of Nature, was the prominent form of religion. With the other days of religious observance came the seventh day, called the Sabbath. No one knows its true historical origin. The statement respecting its origin, in the fourth commandment, and elsewhere in the Old Testament, can hardly be accepted as literally true by any one in this century. No scientific man, in the present stage of philosophic inquiry, will believe that God created the universe in six days, and then rested on the seventh. Did other nations observe this day before the Hebrews; was it also connected with some Fetichistic form of worship; what was the historical event which led to the selection of that day in special? This it is easy to ask, but perhaps not possible to answer. These are curious questions; they are of little practical importance to us at this moment.
