2,921. The Source of a Nazir's Offerings

Hilchos Nezirus 8:13

The three animals for the nazir’s offerings and the bread that’s brought with them must all come from secular property, the same as with other vows of sanctification, as will be discussed IY”H in Hilchos Maaseh HaKorbanos.

Hilchos Nezirus 8:14

Let’s say that someone says, “I’m a nazir on the condition that when I shave, I can bring my offerings from second tithe money.” In such a case, he is rendered a nazir but he may not bring his offerings using second tithe; he must use secular funds.
