124 Kiddushin 3/1-3

(1) [With regard to] one who says to his fellow, "Go and betroth to me a certain woman," [and] he went and betrothed her for himself, she is betrothed [to the second one]. Similarly, [with regard to] one who says to a woman, "You are hereby betrothed to me after thirty days," and another came and betrothed her within thirty days, she is betrothed to the second one. [If it is] the daughter of a Kohen [becoming betrothed] to an Israelite [i.e., a non-Kohen], she may eat of the terumah . [If he said, "You are hereby betrothed to me] from now and after thirty days," and another came and betrothed her within thirty days, she is betrothed and not betrothed. If it is the daughter of an Israelite to a kohen or the daughter of a Kohen to an Israelite, she may not eat of the terumah.

(2) [With regard to] one who says to a woman, "You are hereby betrothed to me on condition that I will give you two hundred zuz [a specific unit of money]," she is betrothed, and he must give [her the money]. "On condition that I give you [two hundred zuz] from now and until thirty days," if he gave it to her within thirty days, she is betrothed; and if not, she is not betrothed. "On condition that I have two hundred zuz," she is betrothed, [as long as] he has it. "On condition that I will show you [two hundred zuz]," she is betrothed and he must show it to her. and if he showed it to her on the [money-changer's] table, she is not betrothed.

(3) "On condition that I own a beit kor [a measure of area, equivalent to that area of land large enough to require a kor of seeds to sow it] of dirt [i.e., a field]," she is betrothed, [as long as] he has it. "On condition that I have [a beit kor] in a certain place," if he has it in that place, she is betrothed; if not, she is not betrothed. "On condition that I will show you a beit kor," she is betrothed, and he must show it to her. If he showed it to her in the valley, she is not betrothed.
