Tafsiran yang Mengutip untuk Bilangan 19:11

The fathers of impurity are a: sheretz, semen, [an Israelite] who has contracted corpse impurity, a metzora during the days of his counting, and the waters of purification whose quantity is less than the minimum needed for sprinkling. Below in sections three and four the mishnah explains the shared characteristics of these types of impurity. A) Sheretz one of the eight creepy crawly things listed in Leviticus 11:29ff. B) See Leviticus 15:16-17. C) See Numbers 19:11, 17. D) Once the metzora (person with skin disease) is healed, he spends seven days outside of the camp until he is allowed back in. During these days he is still impure and he conveys impurity to other things. See Leviticus 14. E) These are waters with the red heifer's ashes in them. See Numbers 19:21. If there is not sufficient water to be used to sprinkle on the dead, then these waters convey impurity in the ways described below. Tomorrow's mishnah will discuss how they convey impurity if there is enough to sprinkle.

What [is the case of] two? A person who touches a corpse is defiled with seven days’ defilement and a person who touches him is defiled with a defilement lasting until the evening.

"Him" refers to the person who came into contact with the corpse.

he was unaware of it and afterward found out. This applies also to someone who touches a man who suffers from a constant flow, someone who touches someone else who had contact with a corpse, someone who touches a woman who suffers from a constant flow, and someone who touches a menstruant.

נפשת מת — The word נפשת, which appears redundant, is intended to include a quarter of a log of the blood of a corpse — to intimate that even this, as a corpse itself, makes men and vessels unclean through being in a "tent” in which it happens to be (Sanhedrin 4a).
