"[Be betrothed to me] with the understanding that I will speak about you to the ruler" [and he also gave her something worth a perutah], if he spoke about her in the way of casual conversation—she is betrothed [meaning: this is the minimum amount of speech that would fulfil the stipulation, but note "כדרך מדברים" doesn't appear in the Ehrfurt manuscript]; but if not—she is not betrothed. [If he said,] "[Be betrothed to me] for the price of me speaking about you to the ruler", if he spoke about her about something worth a perutah—she is betrothed; but if not—she is not betrothed.

"[Be betrothed to me] with the understanding that Ploni is happy with it", even if [Ploni] said "I'm not happy with it"—she is betrothed, lest they form a conspiracy (sic! based on Ehrfurt manuscript). Until he said "I want it", if he says "I want it"—she is betrothed; but if not—she is not betrothed. "With the understanding that my father is happy with it", even if his father does not want it—she is betrothed, for perhaps he will be happy another time. If the father dies—she is betrothed. If the son dies—this actually happened and they came and taught the father to say "I do not want this".
