Deuteronomy 14:21

“Ye shall not eat of anything that dieth of itself, etc.] This law is repeated from (<031715>Leviticus 17:15), thou shalt give it unto the stranger that is in thy gates, that he may eat it; not to the proselyte of righteousness, for he might not eat of it any more than an Israelite, and if he did, he was obliged to wash his clothes, and bathe himself in water, and was unclean until the evening, as in (<031715>Leviticus 17:15) but to a proselyte of the gate, who took upon him, as Jarchi observes, not to serve idols, one that has renounced idolatry, but has not embraced the Jewish religion; such an one might eat of things that died of themselves, or were not killed in a proper manner.

“Ye shall not eat of any thing that dieth of itself--(See on Lev 17:15; Lev 22:8). thou shalt give it unto the stranger that is in thy gates--not a proselyte, for he, as well as an Israelite, was subject to this law; but a heathen traveller or sojourner. Thou shalt not seethe a kid in his mother's milk--This is the third place in which the prohibition is repeated [Exo 23:19; Exo 34:26].

“Compare Leviticus 11:0. The variations here, whether omissions or additions, are probably to be explained by the time and circumstances of the speaker. Deuteronomy 14:5 The “pygarg” is a species of gazelle, and the “wild ox” and “chamois” are swift types of antelope. Deuteronomy 14:21 The prohibition is repeated from Leviticus 22:8. The directions as to the disposal of the carcass are unique to Deuteronomy, and their motive is clear. To have forbidden the people either themselves to eat that which had died, or to allow any others to do so, would have involved loss of property, and consequent temptation to an infraction of the command. The permissions now for the first time granted would have…”

“14:21 Animals that had died a natural death were considered unclean (even if considered clean while living) because they had not been slaughtered according to ritual protocol and their blood had not been properly drained and disposed of (see 12:23-25). • You must not cook a young goat in its mother’s milk: A common explanation for why this pagan practice was improper is that it displayed insensitivity to the natural feelings of affection and trust between mothers and their offspring (see 28:56-57).”
