Exodus 31:15

Six days thou shalt do works, but the seventh day is the sabbath, a holy rest to the Lord; every one who shall do a work on the seventh day shall be put to death.

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 be put to death.

Six days shall work be done, but on the seventh day is a Sabbath of solemn rest, holy to Yahweh. Whoever does any work on the Sabbath day shall surely be put to death.
