Parashat Shl'ach L'cha - Cruel and Unusual?

(27) “How much longer shall that wicked community keep muttering against Me? Very well, I have heeded the incessant muttering of the Israelites against Me. (28) Say to them: ‘As I live,’ says יהוה, ‘I will do to you just as you have urged Me. (29) In this very wilderness shall your carcasses drop. Of all of you [men] who were recorded in your various lists from the age of twenty years up, you who have muttered against Me, (30) not one shall enter the land in which I swore to settle you—save Caleb son of Jephunneh and Joshua son of Nun. (31) Your children who, you said, would be carried off—these will I allow to enter; they shall know the land that you have rejected. (32) But your carcasses shall drop in this wilderness, (33) while your children roam the wilderness for forty years, suffering for your faithlessness, until the last of your carcasses is down in the wilderness. (34) You shall bear your punishment for forty years, corresponding to the number of days—forty days—that you scouted the land: a year for each day. Thus you shall know what it means to thwart Me. (35) I יהוה have spoken: Thus will I do to all that wicked band that has banded together against Me: in this very wilderness they shall die and so be finished off.’” (36) As for the agents whom Moses sent to scout the land, those who came back and caused the whole community to mutter against him by spreading calumnies about the land— (37) those who spread such calumnies about the land died of plague, by the will of יהוה. (38) Of those involved in going to scout the land, only Joshua son of Nun and Caleb son of Jephunneh survived. (39) When Moses repeated these words to all the Israelites, the people were overcome by grief. (40) Early next morning [their fighting force] set out toward the crest of the hill country, saying, “We are prepared to go up to the place that יהוה has spoken of, for we were wrong.” (41) But Moses said, “Why do you transgress יהוה’s command? This will not succeed.

(13) Speak to the Israelite people and say: Nevertheless, you must keep My sabbaths, for this is a sign between Me and you throughout the ages, that you may know that I יהוה have consecrated you. (14) You shall keep the sabbath, for it is holy for you. One who profanes it shall be put to death: whoever does work on it, that person shall be cut off from among kin. (15) Six days may work be done, but on the seventh day there shall be a sabbath of complete rest, holy to יהוה; whoever does work on the sabbath day shall be put to death.

All (types of) work (for whose transgression) a person is guilty on the Sabbath is also guilty on Yom Kippur. And all types of work for whose transgression on the Sabbath a person is free from punishment but are still prohibited, are also prohibited on Yom Kippur in a like manner except that on the Sabbath a conscious sin is punishable by stoning, but on Yom Kippur it is punishable by karet. Everything that is forbidden to be moved (or handled) on the Sabbath is also forbidden to be moved (or handled) on Yom Kippur, (but it is permitted to clean vegetables and to open (shell) nuts from the Minḥah time onward when (Yom Kippur) falls on a weekday, but nowadays (presently) it is customary to forbid that.)
Hagah: If a fire occurs on Yom Kippur, it is permitted to save one meal for the need of the night (following Yom Kippur) as one (may) save on the Sabbath the afternoon meal, (ר״ן פרק כל כתבי), and it is already explained in section 334 (as to) how to act at this time when a fire (occurs) on the Sabbath and the same law (applies) for Yom Kippur. It is customary that the children play with nuts (אגודה ומהרי״ל). One should not object to them (the children) even before the Afternoon Prayer, and the custom is widespread with respect to the mentioned law of breaking nuts, (ד״ע).
