Kiddushin 2:8-9

Kiddushin 2:8

If a kohein betroths a woman by giving her his share from a sacrifice, she is not betrothed, whether it was a portion from a sacrifice of high sanctity or of light sanctity. If a man betroths a woman with second tithe, whether he did so by accident or on purpose, Rabbi Meir says the betrothal is ineffective. Rabbi Yehuda says that if the man gave the woman second tithe accidentally, the betrothal is ineffective but if he gave it to her intentionally, it is effective. If a man betrothed a woman with sanctified property (hekdesh), Rabbi Meir says that intentionally, it is effective, but unintentionally it is not; Rabbi Yehuda says that unintentionally, the betrothal is effective, but intentionally it is not.

Kiddushin 2:9

A woman is not betrothed if a man tries to betroth her using: orlah (produce of the first three years); mixed species of a vineyard; an ox that has been condemned to be stoned; an eglah arufah (calf to be killed as part of a ceremony following an unsolved murder); the birds of a metzora’s purification; a nazir’s hair (which is to be burned); a firstborn donkey; meat cooked with milk; non-sanctified meat that was slaughtered in the Temple courtyard. (It is prohibited to derive benefit from any of these things.) If a man sold one of these things and betrothed a woman with the money, she is betrothed.
