משנה אויף ויקרא 15:29

If a woman had five doubtful genital discharges or five doubtful births, she needs to bring only one offering, and she may eat sacrifices [immediately], and she is not liable to bring the other [offerings]. If a woman had five certain births, or five certain genital discharges, she brings one offering and may then eat sacrifices [immediately], and she is liable to bring the other offerings. It once happened in Jerusalem that the price of a pair of doves rose to a golden denar. Rabban Shimon ben Gamaliel said: By this sanctuary, I shall not go to sleep tonight before they cost but a [silver] denar! Then he entered the court and taught: if a woman had five certain births or five certain genital discharges she needs to bring only one offering, and she may then eat sacrifices, and she is not liable to bring the other [offerings]. Thereupon the price of a pair of birds stood at a quarter of a [silver] denar each.

He may donate his terumah and his tithes with his consent. He may offer up for him the bird sacrifices of zavim and zavoth and the bird sacrifices of women after childbirth, sin-offerings and guilt-offerings. He may teach him midrash, halakhoth and aggadoth, but not Scripture, yet he may teach his sons and daughters Scripture And he may support his wife and children, even though he is liable for their maintenance. But he may not feed his beasts, whether clean or unclean. Rabbi Eliezer says: he may feed an unclean beast of his, but not a clean one. They said to him: what is the difference between an unclean and a clean beast? He replied to them, a clean beast, its life belongs to heaven, but its body is his own; but an unclean animal its body and life belongs to heaven. They said to him: The life of an unclean beast too belongs to heaven and the body is his own for if he wishes, he can sell it to a non-Jew or feed dogs with it.
