The Sabbath was given to all mankind at the Creation of this world.
The seventh-day Sabbath was given to mankind on the seventh day of Creation Week.
“Thus the heavens and the earth were finished, and all the host of them. And on the seventh day God ended His work which He had made; and He rested on the seventh day from all His work which He had made.
“And God blessed the seventh day, and sanctified it: because that in it He had rested from all His work which God created and made.”—Genesis 2:1-3.
God dedicated and set aside the Sabbath as a rest day—2,000 years before the first Jew. Abraham is considered by all to have been the first Jew. He lived about 2000 B.C. Biblical records indicate that the Creation of this world took place about 4000 B.C. So the Bible Sabbath is not Jewish! It is for mankind; it is for all the world.
“The Sabbath was made for man.”—Mark 2:27.
