Remember the Sabbath day, to keep it holy. Six days you shall labor and do all your work, but the seventh day is the Sabbath of the LORD your God. In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who is within your gates. For in six days the LORD made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the LORD blessed the Sabbath day and hallowed it. Exodus 20:8-11
We see from the scripture above that keeping the Sabbath is one of the ten commandments. Exodus 31: 13-17 tells us that keeping the Sabbath is a sign of the eternal and perpetual covenant between us and God and that the children of Israel are to keep the Sabbath throughout all generations. Keeping the Sabbath is likened to wearing our wedding ring to show that we are betrothed to Messiah Yeshua, our bridegroom.
