Tosefta su Salmi 116:78

Four entered the orchard: Ben Azzai, Ben Zoma, Acher (i.e., Elisha ben Avuya), and Rabbi Akiva. One looked and died. One looked and was harmed. One looked and cut down the trees. And one went up in peace and went down in peace. Ben Azzai looked and died. Scripture says about him (Ps. 116:15): "Precious in the sight of the LORD Is the death of His saints". Ben Zoma looked and was harmed. Scripture says about him (Prov. 25:16): "Hast thou found honey? eat so much as is sufficient for thee" and the continuation. [Cont. of the verse: "Lest thou be filled therewith, and vomit it." Elisha looked and cut down the trees. Scripture says about him (Ecc. 5:5): "Suffer not thy mouth to bring thy flesh into guilt" etc. Rabbi Akiva went up in peace and went down in peace. Scripture says about him (Song of Songs 1:4): "Draw me, we will run after thee" etc. They gave a parable: What is this similar to? To the orchard of a king and there is an attic above it. It is upon [the man] to look so long as he does not move [his eyes] from it. Another parable was given. What is this similar tp? To [a street] that passes between two paths, one of fire, and one of snow. If it leans one way, it gets burned [by the fire]. If it leans the other way it gets burned by the snow. A man must walk in the middle and not lean to or fro. A story of Rabbi Yehoshua [who was walking in the street and Ben Zoma came opposite him], he reached him and did not greet him. He said to him [from where and to where] Ben Zoma? He said to him: I was watching the creation, and there is not between the upper waters and the lower waters even a handbreadth. As it is written (Gen. 1:2) "and the spirit of God hovered over the face of the waters". And it says (Deut. 32:11): "As a vulture that stirreth up her nest" etc. Just as the vulture flies over the nest, touching and not touching, so too there is not even a handbreadth between the upper waters and lower waters. Rabbi Yehoshua said to his students: Ben Zoma is already outside. In a few days, Ben Zoma passed away.

Three women may engage in relations using a [contraceptive] resorbant (see Ket. 39a:1, Steinsaltz tr.) -- a minor, a pregnant woman, and a nursing woman. A minor, lest she become pregnant and die. What is a "minor"? One who is from eleven years and one day old to twelve years old and one day. Less than that, or more [than that], she may engage in relations in her usual way, and there is no need to be concerned. A pregnant woman, lest her fetus becomes a sandal (i.e., it is flattened due to lack of space in her womb given the existing pregnancy, see Yeb. 100b:17). A nursing woman, lest she kill her son [by having her milk stop up]. And so too Rabbi Meir would say, one should not penetrate [his wife] inside and ejaculate outside, and the Sages say, he may engage in relations in his usual way, and from the Heavens they (i.e., the angels) stand guard over him, as it is said (Ps. 116:6), "God protects the simple ones."

The first Passover was [divided] among three groups (כתות not בתים, see GR"A and Pes. 5:7) and the second Passover was not [divided] among three groups. A Tamid sacrifice would be slaughtered in the evening, he (i.e., the Kohen) would burn the incense, and he would tend to the candles [of the menorah]. He would come to where the Passover offering was located, and he would cut it open and take out its sacrificial portions, even four or five [offerings at a time]. He would put them on a tray and burn them on top of the Altar. And on the Sabbath he would keep the carcass "dressed" (i.e., not flayed) and leave it and go out. Rabbi Yishmael bar Rabbi Yochanan ben Berokah says, [if] the fourteenth [of Nissan] fell on the Sabbath, he would not flay [the carcass] except until the place of the waving (i.e., the breast and thigh, see Men. 62a:1). [If] the Kohen who was to offer [the sacrifice] on the Altar would pour out [the blood] in a single pouring against the base [of the Altar], it would be disqualified. The Levites would stand on their platform and finished the Hallel in song. If they finished it, they would repeat it, and if they repeated it, they would repeat it a third time, although [in actuality] they never repeated it a third time in all their days. Said Rabbi Yehuda -- "in all their days" -- [indeed,] the third [and last] group never reached to "I love the Lord, for He hears" (Ps. 116:1), because the people were few and they would call it the "lazy group."
