Numbers 19:16 Meaning and Commentary

Numbers 19:16

And whosoever toucheth one that is slain with a sword in the
open fields
That is killed by another, that dies a violent death, either by the sword or other means; one that touched such an one was unclean, or that touched the sword with which he was slain, as the Targum of Jonathan adds: "or a dead body": that dies a natural death, or suddenly, or in any way:

or a bone off a man;
dug out of a grave, and lying by itself:

or a grave;
the Targum adds, either the covering or side of a grave:

shall be unclean seven days;
all which has respect to the defiling nature of sin, which is the cause of death and the grave.

Numbers 19:16 In-Context

14 In the case of a person who dies in a tent, anyone who is in the tent at the time of death or who enters it becomes ritually unclean for seven days.

15 Every jar and pot in the tent that has no lid on it also becomes unclean.

16 If any touch a person who has been killed or has died a natural death outdoors or if any touch a human bone or a grave, they become unclean for seven days.

17 To remove the uncleanness, some ashes from the red cow which was burned to remove sin shall be taken and put in a pot, and fresh water added.

18 In the first case, someone who is ritually clean is to take a sprig of hyssop, dip it in the water, and sprinkle the tent, everything in it, and the people who were there. In the second case, someone who is ritually clean is to sprinkle the water on those who had touched the human bone or the dead body or the grave.
