TSK · Numbers 19:14

This is the law of him who has a discharge, and of him who has an emission of semen, 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 separates himself to Yahweh he shall not go near a dead body.

There were certain men, who were unclean because 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.

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