Today’s daf is sponsored by Abby Sosland in memory of Rabbi Henry Sosland, z'l whose yahrzeit is tomorrow. “He always pushed his family to have a project, to study something on the side of everything we were doing. Dad, may our learning today help to give your neshama an aliyah!” Today's daf is sponsored by Becki Goldstein in loving memory of  Avraham ben Shlomo on his 6th yahrzeit "A trailblazer who through his great ahavat Torah and burning desire to spread it wherever he could founded the Elazar English kollel providing Anglos with an avenue to delve into the world of the Talmud and share in his great passion. I have the zchut to be learning my daf with this gemarot and each day his memory (and his comments) inspire me to reach greater heights. I thank Hashem for this great gift of an eved hashem, my husband's chevruta, and a wonderful friend. יהי זכרו ברוך" Today's daf is sponsored by Lisa Kolodny in honor of Nancy Kolodny on her birthday tomorrow. "I am so glad we set out on this Daf Yomi journey together. I love our chevrutot and hope to celebrate many more siyums with you." If one finds a grave buried on the road, one can move it in order to prevent a situation where there is impurity in unexpected places. However, this is true for one or two graves. But if there are three, this is considered an area where there was an ancient cemetery and one is not allowed to remove the bones and one needs to check the area up to twenty cubits around as there is a likelihood of finding more bones. There are some exceptions to these rules. When it is permitted to move bodies, one must remove the earth underneath the body - tefusa. There is a tannaitic debate about what exactly gets removed. What happens when one finds one body, removes it, then another and removes it, and then finds a third in the same area? Do we now consider it an ancient burial place and cannot remove the third or are we lenient and permit moving it for the sake of purifying Israel? What if only three graves are found and no more? If the kohen has a doubt about a leprous mark, if the person is not yet a leper, we are lenient. If the person is already a leper, we are strict. They try to find a source in a verse for this but in the end, they reject the proof and use that verse to teach a different halacha about lepers. In determining if one is a zav who saw once (impure one day), twice (needs seven clean days), or three times (also needs to bring a sacrifice), we differentiate between determining if it was a zav discharge between the first two and the third. This is because once someone is already a zav and needs seven clean days, we assume any discharge will be on account of zav and not from any external circumstance. But to determine the first and second, we need to know it was specifically from being a zav and not because or food, drink, activity, etc.
