TSK · Numbers 19:14

This [is] the law of him that hath an issue, and [of him] whose seed goeth from him, and is defiled therewith;

Neither shall he go in to any dead body, nor defile himself for his father, or for his mother;

All the days that he separateth [himself] unto the LORD he shall come at no dead body.

And there were certain men, who were defiled by the dead body of a man, that they could not keep the passover on that day: and they came before Moses and before Aaron on that day:

And seven months shall the house of Israel be burying of them, that they may cleanse the land.
