Jews, Seventh-day Adventists, and other Sabbath-keeping groups keep the Sabbath every seventh day in accordance with the creation account in Genesis 1:1-2:3 and the fourth commandment in Exodus 20:9-11. In the last few years, a number of individuals among Messianic Jews and Seventh-day Adventists have started to promote the Lunar Sabbath Theory.
