The Sabbath (Shabbat in Hebrew) is one of Judaism’s greatest gifts to humanity. People in the ancient Near East had nothing similar to the Jewish concept of a weekly sacred day of rest. Other cultures in the past knew of a seven-day week based on the phases of the moon, but the Israelite Sabbath is not connected to the movements of celestial bodies. It stands apart.
The Eternal One spoke to Moses, saying, "Phinehas, son of Eleazar son of Aaron the priest, has turned back My wrath from the Israelites by displaying among them his passion for Me, so that I did not wipe out the Israelite people in My passion." - Numbers 25:10-11
