Compare Leviticus 11. The variations here, whether omissions or additions, are probably to be explained by the time and circumstances of the speaker.
The “pygarg” is a species of gazelle, and the “wild ox” and “chamois” are swift types of antelope.
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 been useless in the wilderness. During the 40 years’ wandering there could be but little opportunity of selling such carcasses; while non-Israelites living in the camp would in such a matter be bound by the same rules as the Israelites Leviticus 17:15; Leviticus 24:22. Further, it would seem (compare Leviticus 17:15) that greater stringency is here given to the requirement of abstinence from that which had died of itself. Probably on this, as on so many other points, allowance was made for the circumstances of the people. Flesh meat was no doubt often scarce in the desert. It would therefore have been a hardship to forbid entirely the use of that which had not been killed. However, now that the plenty of the promised land was before them, the modified toleration of this unholy food was withdrawn.
