Oholos 16:4 - 16:5

הבודק – that which is taught in the [previous] Mishnah: "ובודק הימנו ולהלן עשרים אמה"/And he examines [the ground] from it and onward for twenty cubits, there is no need to dig it all up, but rather, he digs a cubit by a cubit and leaves a cubit hat he doesn’t dig, and he does this until he reaches the end of twenty [cubits]. And that cubit that he digs he must dig until he reaches the rock or the virgin/untouched soil, which is ground that had never ever been dug.

המוציא את העפר ממקום הטומאה – from those cubits that he digs.

אוכל בדמאו – if he is a Kohen, he eats of his heave-offering. It is the language of (Exodus 22:28): “You shall not put off the skimming of the first yield of your vats.” But even though the Kohanim are not permitted to check, they are warned about the defilement, nevertheless, if the Kohen happens by chance to check, he is not forbidden to eat heave-offering where it is not under the presumption of defilement being there.

המפקח את הגל – of stones that fell upon a person and he died. If he was a Kohen, he does not eat of his doubtful heave offering. For since it is under the presumption that there is defilement there, we are concerned that perhaps [the corpse] was overshadowed, and even we are concerned even if he is doubtfully alive or doubtfully dead.

היה בודק- to complete the twenty cubits.

לנחל – river.

לשלולית (to a pool, pond, rivulet) – a rivulet/canal which imparts booty (alluvium) to its banks and other canals of what drink from it.

או לדרך הרבים – and they don’t bury the dead/corpse in it (i.e., the public road).

מפסיק - and he doesn’t examine further to complete the twenty cubits.

והכל טהור – and they don’t have the ground which it occupied (i.e., the earth surrounding the buried corpse), but rather he collects the bones alone and he doesn’t have to take more.

רבי שמעון אומר כו' – But the Halakha is not according to Rabbi Shimon.
