DEUT557 Bring vowed objects to the Beis HaMikdash during the first festival after the vow is uttered. Key concept: When a person vows to perform a mitzvah, he must not be lazy about fulfilling the vow. After all, people are quick to fulfill the commands of kings of flesh and blood, so all the more so should we be quick regarding commands of the Holy One, the King of kings. Still, when someone makes a vow to bring something to the Beis HaMikdash or to perform a mitzvah there, the Torah does not trouble him to travel to Jerusalem immediately to fulfill the vow. That would be an undue burden, and it would cause people to refrain from making such vows, to avoid the strain of having to travel immediately. At festival time, however, almost everyone must go to Jerusalem anyway, so the Torah warns us to fulfill such vows during the first festival after the vow is made. [Regarding vows such as these, the Torah warns, “Do not delay,” but one does not violate this prohibition unless three festivals have passed and the vow was not fulfilled. On the other hand, our verse is a positive command, and if the person that vows does not fulfill his vow before the end of the first festival, he notifies a positive precept of the Torah].
