(Mishnah): A person may say to a shopkeeper, "Fill for me this utensil''. However, he should not mention any type of measuring vessel.

R. Yehudah: If the utensil that he gave was a measuring utensil, the shopkeeper should not fill it.

Shaul ben Botnis (who was a shopkeeper) would fill his measuring utensils before Yom Tov and give them to customers on Yom Tov.

Abba Shaul: He would also do this on Chol Hamoed, to give people more time to learn Torah.

Chachamim: He would also do this on a regular weekday, in order that the utensils would become saturated with oil. He did this so that when he measured out oil for his customers he would not give them less oil than they had paid for.

Gemara (Rav Chuna): When the Mishnah instructed not to measure, this means that he should give less or more than that amount.

R. Elazar to Zeiras bar Chama: It is also prohibited to say, 'Fill for me this utensil and tomorrow we will measure it' (as the latter phrase is problematic).

Beraisa: There was a story of the son of R. Elazar bei R. Tzadok and of Aba Shaul ben Bitnis who were shopkeepers in Yerushalayim. They would fill their measures before Yom Tov and give them to customers on Yom Tov.

R. Chanina ben Akavya: They would also do this on Chol HaMoed in order to saturate the utensils with oil (see (e) above).

R. Elazar ben R. Tzadok also gathered 300 barrels and his friend gathered 300 barrels.

Chachamim to them: You did not need to do this, but since you were stringent on yourselves, the money should be used for public needs.

Once, Abba Shaul became sick and the Rabbanan entered to visit him.

Abba Shaul: Have you seen my right hand that would always measure honestly (but is nevertheless in pain)?

R. Chanina: Whoever suggests that Hash-m overlooks sin, they will overlook (detach) his intestines; rather, Hash-m is slow to anger (to give a person a chance to repent).

R. Acha said about such a person (who does not repent), the Pasuk states (Tehillim 50,3), "and to the righteous who cling to Him, He is as thin as hair'' - he is particular with them down to a hair's breadth.

R. Yosa bei R. Bun: This is not the source, rather it is this Pasuk, "And His awe is upon all around Him'' - His awe is more apparent upon those who are close to Him than those who are distant.

(Mishnah): A person may say to his friend - "Give me a certain number of eggs and nuts'', as it is normal for a homeowner to do so in his own home (so it does not look like a monetary transaction).

(Gemara - Beraisa): A person may say to his friend - "Give me a measure of spices'', as it is normal for a homeowner to put such a measure of spices in his pot.
