Six containers were used in the Temple for collecting voluntary offerings, for which six different explanations are provided to clarify their specific purposes.

If a person vows to bring a specific animal for a voluntary offering and it becomes blemished, the animal must be redeemed and replaced. The Rabbis permit using the redemption money to purchase a different type, size, or number of animals, whereas Rebbi requires the replacement to match the original animal's type, size, and number exactly.

When a person vows to bring "one of my oxen," the best and the middle-quality oxen are sanctified because the specific intent remains unclear. Raba bar Ulla distinguishes this from the phrase "an ox from my oxen," explaining that such language clearly indicates the best ox was intended. The Gemara challenges this distinction by citing laws from house sales, where the definitions of intended property follow different standards.
