Just as the water checks her so the water checks him, as it is said, “And shall enter”, “And shall enter” (Numbers 5:22,. Just as she is prohibited to the husband so is she prohibited to the lover, as it is said, “defiled … and is defiled” (Numbers 5:27,, the words of Rabbi Akiba. Rabbi Joshua said: thus Zechariah ben Hakatzav used to expound. Rabbi says: twice in the portion, “If she is defiled…defiled”--one referring [to her being prohibited] to the husband and the other to the paramour.

On that day, Rabbi Akiva expounded, “And every earthen vessel, into which any of them falls, everything in it shall be unclean” (Leviticus 11:33), it does not state tame (is unclean) but yitma’, (shall make unclean). This teaches that a loaf which is unclean in the second degree, makes unclean [food and liquids which come into contact with it] in the third degree. Rabbi Joshua said: who will remove the dust from your eyes, Rabban Yohanan ben Zakkai, since you used to say that in the future another generation will pronounce clean a loaf which is unclean in the third degree on the grounds that there is no text in the Torah according to which it is unclean! Has not Rabbi Akiva your student brought a text from the Torah according to which it is unclean, as it is said “everything in it shall be unclean.”

On that day Rabbi Akiva expounded, “You shall measure off two thousand cubits outside the town on the east side” (Numbers 35:5). But another verse states, “from the wall of the city outward a thousand cubits around” (vs. It is impossible to say that it was a thousand cubits since it has been already stated two thousand cubits; and it is impossible to say that it was two thousand cubits since it has been already stated a thousand cubits! How then is this so? A thousand cubits for the field [surrounding the city] and two thousand cubits for the Sabbath-limits. Rabbi Eliezer the son of Rabbi Yose the Galilean says: a thousand cubits for the field [surrounding the city] and two thousand cubits for fields and vineyards.

On that day Rabbi Akiva expounded, “Then Moses and the children of Israel sang this song unto the Lord and said saying” (Exodus 15:. For the Torah did not need to say “saying”, so why did the Torah say “saying”? It teaches that the Israelites responded to every sentence after Moses, in the manner of reading Hallel; that is why it says “saying”. Rabbi Nehemiah says: as is the reading the Shema and not Hallel.
