TSK · Numbers 19:14

This is the law of him that hath an issue, and of him whose seed of copulation goeth from him, so that he is unclean thereby;

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 Jehovah he shall not come near to a dead body.

And there were certain men, who were unclean by reason of the dead body of a man, so 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 them, that they may cleanse the land.
