3,629. Challah From a Korban Todah and a Korban Nazir

Hilchos Bikkurim 6:5

One need not take challah from the loaves of a thanksgiving offering and the wafers of a nazir that one makes for himself; this is because these things are sanctified. If these things were made to sell in the market to a nazir and to one bringing a thanksgiving offerings, then challah must be taken. This is because the baker plans to eat them if they don’t sell.

Hilchos Bikkurim 6:6

One must take challah from a dough made for partners and a dough made for a group.
