Reading the words "everyone who profanes Sabbath shall surely be put to death" in (in which the verb for death is doubled), Samuel deduced that the Torah decreed many deaths for desecrating the Sabbath. The Gemara posited that perhaps refers to willful desecration. The Gemara answered that is not needed to teach that willful transgression of the Sabbath is a capital crime, for says, "Whoever does any work therein shall be put to death." The Gemara concluded that thus must apply to an unwitting offender, and in that context, the words "shall surely be put to death" mean that the inadvertent Sabbath violator will "die" monetarily because of the violator's need to bring costly sacrifices.
