[14] Ye shall keep the sabbath therefore; for it is holy unto you: every one that defileth it shall surely for whosoever doeth any work therein, that soul shall be cut off from among his people. [15] Six days may work be done; but in the seventh is the sabbath of rest, holy to the LORD: whosoever doeth any work in the sabbath day, he shall surely [16] Wherefore the children of Israel shall 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 for ever: for in six days the LORD made heaven and earth, and on the seventh day he rested, and was refreshed.
