A man consecrates a woman with produce of the second tithe. What is the ruling?
Halacha 4: The second tithe produce belongs to God ('It is God's' — Lev. 27:30) and cannot be used for personal purposes; the kiddushin are therefore not valid in either case.
Question 2
A man tells a woman: 'You are consecrated to me with the dinar you owe me.' She was not previously engaged to him. What is the ruling?
Halacha 13: When a man consecrates with a debt — even one recorded in a promissory note — she is not consecrated, because a loan is given to be spent and there is nothing presently existing for her to derive benefit from.
Question 3
A man speaks to the ruling authorities on a woman's behalf, successfully preventing her prosecution, and declares her consecrated in consideration of this service. What is the ruling?
Halacha 19: The benefit she received from his advocacy is treated as a loan (like wages owed), not a present benefit she received. She is not consecrated unless he additionally gives her a p'rutah of his own.
Question 4
A man tells a woman: 'You are consecrated to me with this dinar on condition that you return it to me.' She returns the dinar. What is the ruling?
Halacha 24: If she returns the dinar, she has derived no benefit and received nothing. If she does not return it, his condition is unmet. Either way, the kiddushin are not valid.
Question 5
A man offers a woman three dates one at a time, saying 'Become consecrated to me with this one, with this one, and with this one.' None of the individual dates is worth a p'rutah, but together they are. What is the ruling?
Halacha 27: When he uses the conjunctive form ('with this one, with this one, and with this one'), the dates are combined. If together they are worth a p'rutah, she is consecrated.
