Whoever vows to sacrifice a sheep during the days of sacrifice, and he is wealthy, must sacrifice two sheep according to us: one for the vow and one for the obligation of the law initially, unless he intends by it to inform about what is obligatory upon him, in which case he is only required to sacrifice one. If he vowed before the days of sacrifice, he is required to sacrifice two without disagreement; because the wording does not imply informing about the obligatory, as there is no obligation before the time. This issue is known and I understood it. Our problem is: if a wealthy person buys a sheep for sacrifice before the days of sacrifice, meaning: he intended the sacrifice at the time of purchase, does his purchase before the days of sacrifice count as an obligation, which is the vow to sacrifice according to custom? Since there is no obligation before the days of sacrifice, is the purchase by the wealthy and the poor with the intention of sacrifice before the days of sacrifice equal? Have they both become vow-makers? Or is there a difference between them?
