레위기 2:6 미슈나 참조: Mishnah Menachot & Mishnah Negaim

All menahot prepared in a vessel must be broken into pieces. The minhah of an Israelite was folded into two and the two were folded into four, and it was severed [at each bend]. The minhah of priests was folded into two and the two were folded into four, but it was not severed. The minhah of the anointed high priest was not folded. Rabbi Shimon says: neither the minhah of the priests nor the minhah of the anointed high priest was broken in pieces, since the handful was not taken from them, and whenever the handful is not taken [from a minhah] it is not to be broken in pieces. The pieces were the size of an olive.

In the case of a stone in a corner, when the stone is taken out it, he must take it all out; But when [the house is] torn down he tears down his own [part] and leaves that which belongs to his neighbor. Thus it follows that there is a greater stringency for taking out than for tearing down. Rabbi Elazar says: if a house is built of rows of head stones and small stones, and a nega appears on a head stone, all of it must be taken out; but if it appeared on the small stones, he takes out his stones and leaves the others.
