TSK · Numbers 19:14

This is the law for the one with a discharge: for the one who has a seminal emission and becomes unclean by it,

He must not go where there is any dead person; he must not defile himself even for his father and his mother.

“‘All the days that he separates himself to the LORD he must not contact a dead body.

It happened that some men who were ceremonially defiled by the dead body of a man could not keep the Passover on that day, so they came before Moses and before Aaron on that day.

For seven months Israel will bury them, in order to cleanse the land.
