Exodus 31:13-14

13And thou, speakH1696 thou unto the children of IsraelH3478, sayingH559, Surely my sabbathsH7676 shall ye keepH8104; for this is a signH226 between me and you throughout your generationsH1755, that ye may knowH3045 that it is I, Jehovah, who do hallow you.

14KeepH8104 the sabbathH7676, therefore; for it is holyH6944 unto you; every one that profaneth it shall certainly be putH4191 to deathH4191: yea, whoever doeth workH4399 on it, that soulH5315 shall be cutH3772 off from among his peoplesH5971.
