Incidental to the halakhic statement in his name, the Gemara also cites another statement that Rava bar Meḥasseya said that Rav Ḥama bar Gurya said that Rav said: One who gives a gift to another must inform him that he is giving it to him. As it is stated: “Only keep My Shabbatot for it is a sign between Me and you for your generations to know that I am God Who sanctifies you” (Exodus 31:13). When the Holy One, Blessed be He, gave Shabbat to Israel, He told Moses to inform them about it. That was also taught in a baraita: The verse states: “For I am God Who sanctifies you,” meaning that the Holy One, Blessed be He, said to Moses: I have a good gift in My treasure house and Shabbat is its name, and I seek to give it to Israel. Go inform them about it. From here Rabban Shimon ben Gamliel said: One who gives a gift of bread to a child needs to inform his mother that he gave it to him. The Gemara asks: What does he do to the child, so that his mother will know that he gave him a gift? Abaye said: He should smear him with oil or place blue shadow around his eye in an obvious manner. When the mother of the child notices and asks him about it, he will tell her that so-and-so gave him a piece of bread. The Gemara asks: And now that we are concerned about witchcraft involving oil or eye shadow, what should one who gives a gift do? Rav Pappa said: He should smear him with food of the same type that he gave him to eat.

(12) And the LORD said to Moses: (13) Speak to the Israelite people and say: Nevertheless, you must keep My sabbaths, for this is a sign between Me and you throughout the ages, that you may know that I the LORD have consecrated you. (14) You shall keep the sabbath, for it is holy for you. He who profanes it shall be put to death: whoever does work on it, that person shall be cut off from among his kin. (15) Six days may work be done, but on the seventh day there shall be a sabbath of complete rest, holy to the LORD; whoever does work on the sabbath day shall be put to death. (16) The Israelite people shall keep the sabbath, observing the sabbath throughout the ages as a covenant for all time: (17) it shall be a sign for all time between Me and the people of Israel. For in six days the LORD made heaven and earth, and on the seventh day He ceased from work and was refreshed.
(43) in order that future generations may know that I made the Israelite people live in booths when I brought them out of the land of Egypt, I the LORD your God.

(22) On the sixth day they gathered double the amount of food, two omers for each; and when all the chieftains of the community came and told Moses, (23) he said to them, “This is what the LORD meant: Tomorrow is a day of rest, a holy sabbath of the LORD. Bake what you would bake and boil what you would boil; and all that is left put aside to be kept until morning.” (24) So they put it aside until morning, as Moses had ordered; and it did not turn foul, and there were no maggots in it. (25) Then Moses said, “Eat it today, for today is a sabbath of the LORD; you will not find it today on the plain. (26) Six days you shall gather it; on the seventh day, the sabbath, there will be none.” (27) Yet some of the people went out on the seventh day to gather, but they found nothing. (28) And the LORD said to Moses, “How long will you men refuse to obey My commandments and My teachings? (29) Mark that the LORD has given you the sabbath; therefore He gives you two days’ food on the sixth day. Let everyone remain where he is: let no one leave his place on the seventh day.” (30) So the people remained inactive on the seventh day.

(10) Lot looked about him and saw how well watered was the whole plain of the Jordan, all of it—this was before the LORD had destroyed Sodom and Gomorrah—all the way to Zoar, like the garden of the LORD, like the land of Egypt. (11) So Lot chose for himself the whole plain of the Jordan, and Lot journeyed eastward. Thus they parted from each other; (12) Abram remained in the land of Canaan, while Lot settled in the cities of the Plain, pitching his tents near Sodom. (13) Now the inhabitants of Sodom were very wicked sinners against the LORD.

With regard to the halakha itself, the Gemara asks: Is that so? Didn’t Rav Ḥama bar Ḥanina say: One who gives a gift to his friend need not inform him, as God made Moses’ face glow, and nevertheless it is stated with regard to Moses: “And Moses did not know that the skin of his face shone when He spoke with him” (Exodus 34:29)? The Gemara answers: This is not difficult. When Rav Ḥama bar Ḥanina said that he need not inform him, he was referring to a matter that is likely to be revealed. When Rabban Shimon ben Gamliel said that he needs to inform him, he was referring to a matter that is not likely to be revealed. The Gemara asked: If so, isn’t Shabbat likely to be revealed, as it will be necessary to inform them of Shabbat together with the other mitzvot? Why was Moses asked to inform them about Shabbat separately? The Gemara answers: The giving of its reward is not likely to be revealed, and it was necessary to inform them about so extraordinary a gift.
אמר רבא בר רב הונא מצאו מהול אין בו משום אסופי משלטי הדמיה אין בו משום אסופי שייף משחא ומלא כוחלא רמי חומרי תלי פיתקא ותלי קמיעא אין בו משום אסופי
§ Rava bar Rav Huna says: If an abandoned boy was found circumcised, he is not subject to the halakhot of a foundling. If the baby’s lineage were unfit, his parents would not have gone to the trouble of circumcising him. Likewise, if his limbs are adjusted, indicating that he was cared for after birth, he is not subject to the halakhot of a foundling. Similarly, if he was anointed with oil, or if his eyes were smeared with eye salve, or if he was adorned with rings, or if a note [pitka] was hanging on him, or if an amulet was hanging on him, he is not subject to the halakhot of a foundling.
