Exodus 31:16-18

Modern English Version

¹⁶ Therefore the children of Israel must keep the Sabbath, to observe the Sabbath throughout their generations, for a perpetual covenant. ¹⁷ It is a sign between Me and the children of Israel forever, for in six days the Lord made heaven and earth, but on the seventh day He rested and was refreshed.”

¹⁸ When He had made an end of communing with him on Mount Sinai, He gave Moses the two tablets of testimony, tablets of stone, written with the finger of God.
