  14 H8104 [H8804] Ye shall keep H7676 the sabbath H6944 therefore; for it is holy H2490 [H8764] to you: every one that profaneth H4191 [H8800] it shall surely H4191 [H8714] be put to death H6213 [H8802] : for whoever doeth H4399 any work H5315 in it, that soul H3772 [H8738] shall be cut off H7130 from among H5971 his people.
